Re: Tank Bag
Sunglasses, sunscreen, heavier or ligher weight riding gloves, spare foam earplugs, balaclava or neck wear (if cold weather), garage door opener, small flashlight, tire pressure guage, wife's lipstick and your chapstick, spare change for tollboth in a film canister, map of the next state, your .40 cal and extra ammo.
Basically, all the stuff you may need, but don't want to have to dig thru the panniers to find on short notice!

1979 Kawasaki 750
