It's a few miles outside Gilmer, Tx - which is about 1/2 hour from Tyler. link here

Yikes... unfortunately there isn't a good way to get east from either SA or Austin... you pretty much have to come up to Dallas and then take 20 or 30 east... nearly 400 miles from SA. We do go to Katemcy a couple times a year, though - which is fairly close to you guys.
