Botany

he Virginia/Maryland/DC wildflowers are essentially at their peak NOW! We will hike the Windy Run Trail in north Arlington down to the Potomac Heritage Trail along the Potomac River. Upstream for a bit and downstream for a bit will show us many of the currently blooming wildflowers. This is timed for later in day so that you can take care of your other responsibilities and still get outside. There will be plenty of light for good pictures. Also, the birds get more active and noisier towards dusk. Bluebells, spring beauty, wild phlox, snowbells (even though it is done snowing) , May apples (even though it is April). These are a few of the flowers blooming now that you will see. The Spring ephmeral wildflowers take advantage of the light and bloom quickly before the trees leaf out and put them in shade. When the trees leaf out, the spring wildflowers begin to go to bed until the next year. Wear shoes with tread that will grip. There are a handful of stream crossings and a set of steep stairs (with a handrail part of the way down). If you have treking poles, consider bringing them. No dogs. I will also show you I-Naturalist. Load the App before you come if you wish. The Appalachian Mountain Club uses this as a citizen science project that can track blooming dates and locations. Meet at 2433 N Kenmore St, Arlington, VA

PLEASE READ AS THERE IS AN IMPORTANT CHANGE for the blind tasting at Maxwell Park only: prepayment will be required. Please note that refunds for cancellations are allowed up to 12 hours before the event start time. (This would be 6:15 AM so best to cancel the night before and definitely as soon as you know.) Please bear with me as we navigate this new process. The real maximum number of attendees will remain at 14, but since the Meetup App won’t let me make it a requirement to pre-pay when you RSVP "Yes," I’m not going to set a cap on Meetup's RSVP list, and we will see how that goes. Because there is no linkage between the Meetup App and Maxwell’s prepayment link, you can’t rely on Meetup's RSVP feature to know if there are still spots available. You will only know with certainty that the attendee cap has been reached if you are rejected while trying to prepay. Here is the pre-pay link: [https://www.giftrocker.com/secure/Order/?h=4375667a](https://www.giftrocker.com/secure/Order/?h=4375667a) Let me know if you have any specific questions. Thank you for your patience as we transition to this new process! Maxwell Park is 4 blocks from the Mt. Vernon Sq/7th St-Convention Center. 🍷 RSVP Please: --**If your plans have changed, please change your RSVP to No.** *Note start time of 6:15 PM!* Please plan to arrive on time. 🍷 What is blind wine tasting? In a blind tasting you use your sense of smell, sight, and taste to try to deduce which variety(wine grape) is in your glass. 🍷 Do I need to be a wine professional? Definitely not - this group is experience diverse and we welcome both wine newbies and wine pros (and everyone else in between). 🍷 How does this work? --Please arrive slightly before 6:15pm to grab a seat. --Maxwell Park will serve us two wine flights: 3 white wines around 6:20 pm and 3 red wines around 7:30 pm. Each flight is $20. A 20% gratuity and tax is added to that. Food and other wines are also available for purchase. --We will discuss each flight as a group and try to reach somewhat of a consensus. Then comes the *big reveal* where we discover if our guesses were right. Full vaccination is required, masks are optional. Unfortunately, while we will try to be as careful as possible, we cannot promise that this will be 100% Covid risk free, please keep that in mind when deciding whether or not to attend. Stay home if you are experiencing any symptoms of Covid 19. Please keep an eye on this event for possible changes. Hope to see you there ! \~ Linda Lists of possible wines: [White Wine Varieties](https://www.mastersommeliers.org/sites/default/files/ES%20Tast-CMS%20Probable%20List%20of%20Examinable%20White%20Grape%20Varieties-NEW_2015.pdf) [Red Wine Varieties](https://www.mastersommeliers.org/sites/default/files/ES%20Tast-CMS%20Probable%20List%20of%20Examinable%20Red%20Grape%20Varieties-NEW_2015.pdf)

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“What Digital Detectives Find,”** on the afterlife of your digital data and the methods of those who investigate it, with Jim Jones, associate professor at George Mason University and cyber security and digital forensics expert. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-digital-detectives](https://events.ticketleap.com/tickets/profsandpints/dc-digital-detectives) .] What happens when you delete digital data such as a picture, video, or email message? The truth is that “deleted” doesn't mean “gone,” and digital forensic investigators can extract and make sense of the residual fragments left over from data often assumed to be gone forever. Learn about the field of digital forensics—and the lessons it offers those who worry about sensitive data being exposed—with Jim Jones, who has been a cyber security and digital forensics practitioner, researcher, and educator for more than 30 years. You’ll learn how all investigations today, criminal and otherwise, to some degree involve digital forensics, an interdisciplinary field that draws from computer engineering, computer science, information technology, law, and ethics. Digital forensics doesn’t just respond to specific incidents, but also seeks out threats within organizations, analyzes malware, and buttresses cyber security. Much of the work of Dr. Jones, his colleagues, and students involves examining digital systems of all types to understand how data persists and decays and how it can be found and recovered. Dr. Jones will discuss how what happens to the digital data that you deleted depends on the type of device you are using, along with a host of other factors. You'll learn how digital data is stored on different devices and what does and doesn’t happen when you delete that data. You'll see examples of data extracted from different devices, demonstrations of what can be inferred from these remnants, and how investigators can tell if such remnants are genuine or not. Finally, you'll learn about strategies to mitigate the risk of exposing sensitive data. Dr. Jones will sort those that work from those that don’t. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: A digital forensics examiner works with evidence in the FBI’s New Jersey Regional Computer Forensics Laboratory (FBI photo).
