I beleive the chance of arrest depends on a lot on the situation and officers state of mind for example; time of night, if it got some
before work, and your responses to questions. I have been pulled over while in route to hunting with dogs in tow and he wanted to know more about the dogs and hunting than anything else. I've been pulled over with rifles in cases in the back seat and knives in plain view. Also I wouldn't ride around Houston with the gear in the truck (keep all my gear in 1 large bag) but then most of us live in small towns were the hog problem is obvious and we aren't driving '88 Olds with 24" rims and a bump system (not trying to stereotype but come on). I probably should remove the switchblade....
