There are two affiliates in Clarksville. I work out at CrossFit Clarksville. Really selection on which one just depends on where you live, in my opinion. CC is closer to Ft. Campbell, off Tiny Town Rd, and MaxFX CrossFit is on the other side of the interstate (around exit 11 as opposed to exit 1). I haven't tried out MaxFX CF because its farther and they require an elements class. It'll be easier to check both of them out when you have real internet. If you have any other questions let me know. Both affiliates would require an email or phone call initially anyway.
