Of course anything can be done. But, to be able to be 5-15 miles back in there with good food for fuel, a comfortable tent and sleeping bag, and a table makes a 10 day stretch much much more bearable. You end up hiking alot chasing critters around anyway. The best place we found for the elk, and yes their were elk everywhere, but one place was UNBELIEVABLE, was another 2.5 hour horseback ride from our basecamp 8 miles in. Can you imagine trying to pull an elk out of there on your back? You might as well bring a fork along, cause you could eat it faster than humping it out on your back. Why mess with it when these opportunities come along so infrequently? I mean, I have put in for 8 states and come up 0-2 so far, and am not holding my breath on the others. I bought a conservation tag last year, and it cost me big $$ (well big for me, maybe not for the guys that buy the governors tags).
As far as deer go, I think the roaded area is better for archery, as it seems like there are more, and easier to get on quickly. I shot mine in the roaded area after spending alot of time in the roadless. My .02 cents.
