Although i do drive trucks (for treework and 5 ton truck for rolloff bins) , my bike is my child (actually my ornery cuss of a cat is my child but...), i ride it daily (average about 70kms a day, its my main transportation. . I lock up with a very thick 3/8" Abus squarelink chain) high grade chain and mini U lock, and i have a smaller chain (5/16" grade 70 transport chain, with ABUS Discus lock ) on the bike to lock the front wheel to the frame. Every allen bolt head is filled with epoxy and a steel ball bearing. I have waterproof cards with my name, address, contact info, etc in in the handlebars, fork steerer tube, and seatpost and seattube. The wheels have my info on the rim strip and on the inside of the tire casing, with a jiffy marker. The inside of my hub axles (bullseye) have a mini waterproof info card wrapped around it with a elastic band. I ONLY lock to the big lamp standards (12" diameter, 1/4" thick steelwall tubing) and i never am away from the bike for more than a few minutes.

yup, its my baby all right. A lot of time, money and effort getting it just the way i wanted it.
