Thanks, Smaug...good suggestion about the beadrider...will have to look it up.
I always carry a tubeless tire patch kit, a mini air pump, a first aid kit and communications gear (cell phone, 2/70cm handheld radio-a lot of areas I go have better ham radio repeater coverage than cell phone coverage...de W6LPH). Also carry some tools, a jumper cable and other odds and ends.
When I was shopping for bike insurance some years ago, I chose my insurance company, in part, because my policy includes bike tows, so good to go on that.
I'll be laying out the tour stuff next week some time to ensure that I'm not overdoing the packing...
