The street address I have given, 12054 South Doty Avenue, is for a strip club called "The Factory" that is right there. Use this address if you need to plug something into your GPS. As you drive along the Frontage road, you won't see street numbers.
If you take exit 130, Doty Road (the frontage road) is clearly marked. Just get off the exit and immediately hook right back around onto Doty where you see signs for Doty Rd and a number of businesses located there. Come back 1 mile. Not sure about signage off exit 115.
This month we are collecting Phragmite Reed! Phragmite is a reed used for thatching in traditional building, but it has become invasive here in the US, in particular in the Great Lakes Region. Location TBD, but will probably be the frontage road of the Bishop Ford between exit 130 and exit 115. Better directions to follow. Goggles, eyeglasses, sunglasses or other eye protection required. Waterproof shoes are very helpful but in an urban environment we can usually get away with standing on asphalt. Dress warmly as we will be outside! Pot luck car snacks! My cell is[masked]-6824. Call me the day of if you are having trouble finding us.
