There are laws about how far from a residence you must be but it hasn't stopped folks in the past, at least not around here. As from shooting from the road, I think you have to be at least out of your car!!! The locals here have fun poking at the guys who park their big expensive trucks along side of the road and walk into the fields about 100 feet or so...you know, until they can find a log or hay bale to park their lazy behinds on....some go in a bit more...but there are plenty who don't...you can see them as you drive by! At the end of the day, they drive back to their camps that they spent some cash on and pay both property and school taxes on....you'd think they'd put a little more effort into the hunting. I'd say they were just out there enjoying nature, but they come during hunting season and hardly go into the woods!
The last time my husband was in the woods hunting, three hunters (later found to be from New Jersey..big surprise) were walking through the woods yodeling. Yeah...deer respond to that in a big way, just not the way that any hunter would be hoping for!
As for the litter....we belong to a fly fishing group and spend at least one Saturday a year picking trash up around streams in the area. A few years back our group had to hire a bull dozer to come in and get all the crap out....everything from bags of garbage to tires to old washing machines. It's downright disgraceful.
