I've hunted the Tyler Rd. area you talk about some, mainly past where the gas and power lines cross, away from Parker Dam. I haven't killed a deer inthere YET, but it's a decent area to hunt. A fair amount of sign.
Another area I've hunted some is on Blackwell Rd., up the hill on the left, before you hit the "Posted" ground. I counted seven scrapes along an old woods/field line several years ago in there, and lots of rubs. I agree, there aren't as many deer around as there used to be, but if you do a little searching and have any knowledge at all of what deer need, you should be able to do O.K.
