Listers,
with T-town behind us and the summer coming up, I will take this opportunity to plug (yet again) the Brooklyn Bike Jumble on May 31st in Park Slope, Brooklyn.
More details here: http://www.nybikejumble.com/
As for parking, as some people may have issues with this, There is no designated parking area.
There will be an unloading/loading area within the park, so getting stuff to the Jumble shouldn't be difficult. However, parking your car/van will have to be on the street. I have received assurances that this won't be difficult.
In case the street does not offer parking options I do know of an unofficial place to park your car that is in the area. Please contact me for more information at this email address.
Thanks,
Harry Schwartzman
Long Island City, NY
