A few years ago I started taking a once a year I take an "epic" bike trip with a friend or two, so far always a credit card tour. The first one went through your backyard (if I'm looking at he right CL listing for the blue Semi-Pro. Always looking for places untravelled, Tour de PNW island sounds like a good theme! Will you be announcing reservations here?

A list of tools and spares:

floor pump
cheap bike stand
allen set
Chain tool
various freewheel tools and a small vice
open and closed wrenches
Crescent wrench
old tooth brushes for cleaning the bits
Pliers
crank puller? Warning that it won't work on TA or Stronglight, those folks should know better!
shop towels!
cleaning fluids, degreaser, chain lube
Spare tubes of various sizes-whatever you use gets tacked onto your bill, but at a lower markup than that toberlone chocolate bar that tempts you in the hotel fridge
Spare cables
Water bottles with your logo on them - a small profit center in itself! Leave an old, usable one for a dollar off...
Goo, Fizz electrolyte tablets, Cliff bars.
Bag Balm! or Chamois butter
Phone number for a local mechanic who would be willing to make a house call, or overnight emergency repairs

Call the area with all this the "bike spa".
