So far, my must haves have been:
Helmet
Gloves
iPod (I listen to it in one ear, leaving the other open to hear)
Cellphone
Water
License & debit card
Portable hex wrenches thingermabob
Cyclocomputer
Windbreaker than I can stuff in my handbar bag
Keys (if I am driving to a trail first)
Bike lock (around my seatpost)
Cheap HD yellow safety glasses (indigoiis! Probably the same ones
)
My RoadID just came in the mail today, so that will go with me, too. I also plan on getting an extra tube to keep in my bag, as well as the tire levers, a small pump, and a multitool (thanks to your suggestions).
"A bicycle does get you there and more. And there is always the thin edge of danger to keep you alert and comfortably apprehensive. Dogs become dogs again and snap at your raincoat; potholes become personal. And getting there is all the fun."
