Here in Virginia you can ride to work in the morning freezing your butt off and be burning up on the ride home this time of year. Since I have always rode naked bikes I have gone home with jackets, gloves, and assorted extra gear stuffed behind the fly screen, wrapped around my waist, and packed under the seat. I was in good old "Wally World" the other day and they had back to school back packs on sale for $9.00 each. I have always seen the ****** Rocket guys wearing them but never gave one a try. Nine dollars poorer I left the store with one in hand. (I could have gotten the Barbie or Spiderman issue but I elected for good old plain black.) It was initially adjusted to fit an anorexic nine year old girl, but the straps expanded more than enough for a good fit on me. It is one of the best riding investments I have ever made. I use it continuously on short trips, grocery store runs, and anytime you need to transport items that would normally go in saddle bags. A 12 pack of Coors Light will fit but does weight you down a bit. Just FYI for the teaching Old Dogs New Tricks Group.
