In my seat pack where I don't have to think about it:
*Multi-tool including chain tool. It's much more of a tool than I need for the short rides around the perimeter of town, but once I get out into the boonies, it's reassuring to have it "just in case."
*Spare tube
*CO2 inflater with two cartridges
*Tire levers
*Epi-Pen
*small lock
*patch kit
Mounted on my bike:
*Mini-pump
*Two bottles of water
*Garmin GPS. If I didn't have that, I'd carry a map. Sometimes I have a map too, anyway.
In my pocket:
*Phone
*Small jar of chamois cream
*Magnifying glass or reading glasses :rolleyes::cool:
*In a ziploc bag that stays together all the time, the following:*Driver's license
*Insurance card
*Organ donor card
*Credit or debit card
*At least $20 cash
*Annual National Park pass
*Bicycling club membership card
Dang, sounds like a lot, doesn't it. It really doesn't seem like it (except for the multi-tool, which weighs a TON, but like I said, it's reassuring to have).
