RE: What do you wear ?
This is a tough one - especially in regard to the ATV odors. It is going to undo all that careful preparation - like showering with special soap, washing all your hunting garments every night at the laundramat in scentless soap, etc. I might be tempted to just walk it rather that ride the ATV. I guess you could carry all your hunting clothes - boots and all - in a sealed bag and put them on in the woods after the ATV ride. The ATV is going to leave some residual odors in the area any way you look at it. Can you get by without it?
