I live about 8 miles from CR and have hunted it all my life. Matter of fact, my grandparents ran the concession stand for years. I have spent my share of time there. I can definitely vouch for an abundance of snakes, but thankfully have steered clear of them! People used to bring both live and dead snakes to the stand. I can vividly remember seeing and hearing rattle snakes in burlap sacks as a kid. Don't care to see any again! There are roughly 13,000 acres that make up CR. I would focus on the Raven Rock area personally. It's steep, but one can typically find birds on that hillside in the spring. Also, focus efforts on the south side(which RR is on), as the state has been timbering towards the north, which parallels I-68. It's worth checking out for sure.
