camocop, i do basicly the same things but here are some of the things i do in addition. i bought a twin bed sheet that is washed in scent free soap andbungi it to my seat to try to prevent any scent transfer to the driving coveralls and base layer i wear driving to the parking area. then i slip out of the coveralls and tennis shoes, put on the hunting clothes and boots that are kept in 2 seperat large zipplock bags. during the offseason i keep everything i hunt with (except the rifle and bow) in rubbermaid tubs to try to prevent contamination. it sounds like alot (it is) but like you, last year i killed 3 doe and 1 buck and passed on several other smaller animals. all of them were within 40 yrds, easy smell range. as ive got better at scent contamination controle, ive seen and killed more deer.
