I rescued mine from an old beach cruiser bike, after my riding buddy Jayjay raved about enjoying the basket on a bike she borrowed.
Apparently I am not the only one. I spotted this photo of west coast rando Oliver with a basket (photo 2). It looks like he is carrying a nice bag in it.
(Thanks to Rando Lynne for her photo of Oliver )
East coast rando Paul has two baskets, one in front and one in back (photo 3). The original "BasketBoy". And it looks like bungee cords to hold things in place. Very nice.
(Thanks to Rando Bill for his photo of Paul )
Update Nov 24, 2011: Here is another rando bike with basket from Alaska on [MG's blog] With Christmas lights too. Sweet!
