We'll hike four miles at Walnut Woods, which is generally a pretty easy hike - doing the Sweetgum Trail Loop and then out and back on the Monarch Loop to get us to 4 miles. Pace around 17-18 minute miles with no one left behind, and faster walkers can lead out ahead. Optional lunch at Brewdog or Canal Winchester.

Join us for an introduction to writing grant proposals for your nonprofit organization, led by consultant Tiffany Nobles. We'll discuss the most common funder requirements and how to successfully meet them. We'll also share common pitfalls to avoid. This event is free and open to the public.

Join us this Thursday at 6:30 pm for a nice hike along the Big Walnut Trail along the Gahanna golf course, circling Creekside and back. This 2 mile hike is fully paved and a beautiful walk through the heart of Gahanna.

**History** The history of [Blendon Woods Metro Park](https://www.metroparks.net/parks-and-trails/blendon-woods/) began long before its 1951 opening, rooted in a landscape of rugged ridges and deep ravines that made the land unsuitable for traditional farming. In 1945, a report proposing a metropolitan park system for Franklin County specifically highlighted these cliffs of Bedford Shale as some of the "wildest land in the vicinity". Following this recommendation, the recently formed park district purchased the first 229 acres in early 1949. Because the terrain was so uneven, developers had to cut a mile-and-a-half-long roadway through dense woods just to bring in heavy equipment. This initial preservation effort ensured that the mature second-growth hardwood forests remained largely untouched by the urban expansion spreading toward Westerville. Opening day arrived on Labor Day, September 3, 1951, marking Blendon Woods as the second park in the Columbus and Franklin County Metro Parks system. The final push to open was a frantic race; the State Highway Department only finished the primary gravel access road four days before the gates opened. Early staff members, consisting of just four full-time employees, had to hand-dig pit toilets and learn construction skills on the fly to build the first picnic shelters. Despite the dusty conditions and limited facilities, the park was an immediate success, drawing massive crowds from across Central Ohio. By the end of the 1950s, annual visitation had already climbed to over 190,000 people. As the surrounding suburbs grew in the 1960s, the park faced severe overcrowding that threatened its natural habitats. In response, Franklin County voters passed the first Metro Parks levy in 1960, providing the funds necessary for a decade of steady expansion. During this era, the park nearly doubled in size, growing from 264 acres to over 570 acres by 1968. Planners also addressed a critical water shortage by collaborating with the U.S. Soil and Conservation Service to build a lake in 1964. This body of water originally served as a temporary reservoir before its role shifted toward conservation and wildlife support. The 1970s marked a transition toward the specialized wildlife and educational focus for which the park is known today. In 1971, the Walden Waterfowl Refuge was established around the 11-acre Thoreau Lake, creating a sanctuary that remains restricted to provide a quiet habitat for migratory birds. A formal nature center was also developed during this period, expanding on the guided Sunday walks that had been a park staple since the early 1950s. The park’s famous "Monarch Mansion" also became a prominent fixture, starting a long tradition of raising and releasing thousands of monarch butterflies each September. These initiatives cemented the park’s reputation as a premier destination for birders and nature enthusiasts. In more recent decades, Blendon Woods has continued to modernize while maintaining its wilderness character. The 10-acre Natural Play Area was added in 2017, encouraging kids to explore the ravines and woods off-trail. This was followed by the opening of a $1.5 million inclusive playground in April 2025, designed to accommodate children of all physical abilities. The nature center also underwent major renovations to include immersive, three-dimensional exhibits and a new butterfly house. Today, the park encompasses 653 acres, preserving a unique geologic and biological corridor amidst the bustling Westerville and Northeast Columbus area. **Map of the Park** Here is a map of [Blendon Woods](https://www.metroparks.net/wp-content/uploads/2025/05/BLN_map_Inclusive-Playground-and-Butterfly-Trail_May-2025_1980px.png). **Summary** For this event, we will hike the Lake View, Hickory Ridge, Ripple Rock, Overlook, Brookside, and Sugarbush Trails. This sounds like a lot, but it will really be only a little over five miles. Blendon Woods has a few hills here and there, but it's not one of the more strenuous metro parks. **Where We'll Meet** We'll meet just in front of the Nature Center. This is about a mile into the park from the main entrance. You have to go past the Ranger Station and the Shadblow Reservable Area to get to it, so don't stop too early at the Ranger Station and get it confused with the Nature Center. **After the Hike** Afterward, we will head over to [Forbidden Root Restaurant & Brewery](https://forbiddenroot.com/restaurants/columbus-ohio/) at Easton for [drinks](https://forbiddenroot.com/restaurants/columbus-ohio/#dinner-menu) and [food](https://forbiddenroot.com/wp-content/uploads/Cbus-Food.pdf). We should be there by 5 if you can't make the hike and just want to join us for drinks. The brewery's actual address is [4080 Worth Ave, Columbus, OH 43219](https://www.google.com/maps/place/4080+Worth+Ave,+Columbus,+OH+43219/data=!4m2!3m1!1s0x88388a86d10b6619:0x4d42b470a5cf11d3?sa=X&ved=1t:242&ictx=111); however, I recommend pointing your GPS to the [Worth Garage](https://www.google.com/maps/place/Worth+Garage/@40.0542293,-82.9137962,17z/data=!3m1!4b1!4m6!3m5!1s0x88388b4df6082825:0x17582f0eccd9dda1!8m2!3d40.0542293!4d-82.9137962!16s%2Fg%2F11rzfvvv8b?entry=ttu&g_ep=EgoyMDI2MDQxNS4wIKXMDSoASAFQAw%3D%3D) across the street. Parking in this garage is free as long as you're not on the first floor, and it is literally right next to the brewery.

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
