welcome to the addiction of mountain biking. My first trail bike was a Giant Boulder SE hard tail. Have you gone to clip in pedals yet? If not, that would be the best thing to do first. I basically learned mountain biking on my Boulder, but once I got addicted, I had to upgrade to a full suspension GT idrive, but the Boulder is a good bike to start with.
If you ever make it up to Greensboro, be sure to check out the Wild Turkey trail, Owls Roost, Bald Eagle & Reedy Fork. In that order!
