don't think that you can spend 10 minutes and find something great. first trip (for me) was just observing the culture of the place and operation. We've been frequenting it about 30 years since.
I ride bike down there and don't remove my helmet when shopping (shades the light) ... other shoppers pick up on it and grab bike related stuff for me - just to make contact and be nice.
Good Hunting !!! (I may bike down there today )
LATER: no audio today. did grab a Vietnam era poncho liner (very collectable and useable) , an 1850's German bible , Italian leather bike saddle , Gossen Luna Pro ..etc...etc.
It was hot on the trip home , so I stopped at the river and soaked feet & gloves , continued on and had a nice lunch, then when crossing a main street (82nd) ...whoosh. Flat tire. Pushed over to a big walnut tree and found a nice patch of grass and swapped tubes. That screwed my mellow day
