.....and everybody would borrow my tools or ask if I had this wheel collar or that set screw..........now I carry the minimum tools I can and I keep a small stash of hardware in the car. I might carry a few extra tools if I have a brand new airplane, but once one has been thru the "shake down" period, they rarely require attention at the field. Oh, I do keep a manual pump in the car, just in case the old Sonic Tronic electric burns up. But so far they seem to last about eight or nine years a pop. I do have band-aids in the box, (not for me mind you), and sun screen. Now with the big West Nile scare, I would recommend you keep some Back Woods Off in the car. I'm lucky, I have drive wagon with several storage compartments. Oh, and you'l need a station wagon too. But not that many tools.
