I'm gearin up to do my 1st road trip. I'll be solo & don't really know where I'm headin (just wanna see where my bike takes me while I have a little down time). I've got an '09 dyna w/ no bags & I'm lookin to travel light (backpack on my back or strapped to the rear fender). I imagine nights spent in cheap motels. any tips? things to bring/not bring that you didn't think of until after your 1st trip? advice u learned out on the road?
