I hunt both ways. I love the week long elk camp, hiking and going further into the wilderness areas. I also like road hunting on lazy weekend days when I dont have time to set a camp. However, I tend to road hunt my deer on the final days being I bow hunt, and deer will stand there and watch you get out and shoot them. Elk however dont like a show, you have to work for them.
I do get out of the truck to shoot my deer, I have taken two over the years like this. Its rather hard to shoot a bow from inside the truck anyway!
I dont own a quad, and I agree, they are so disruptive to hunting. I can understand using them to get from camp to a trail head, but I hate it when your hiked in a mile or so, and along comes some guys on them up the trail. I always check my tags to make sure I dont have a quad rider tag...so far I have not seen one in my tag wallet...
