It's usually difficult for me to get out to Turkey Creek in the first place. This is mainly due to the amount of traffic and incredibly bad/rude drivers in west Knoxville.
I'm also usually out of town on weekends since I have to keep my business up and running then.
Alternate suggestion:
If you were to move this to the UT Campus either tomorrow or next Friday, you might have a better shot at more people coming--especially from the school. Plus, from what I gather, there's not exactly that many spots to train at Turkey Creek. There's plenty on campus (I train almost daily here).
Just throwing that out for ya.
