Tuacahn is worth the price of admission, and even worth traveling to SoUtah. Some of the local playhouses can do some decent stuff, it just depends on if you are a judgmental neanderthalian tool or if you can appreciate watching people do something most people would be afraid to try, even if they don't do it perfectly, while being entertained on a night out supporting a local business with people you care about.
The Terrace Plaza Playhouse in Washington Terrace puts on some nice plays. My daughter was in their rendition of A Christmas Carol and I really enjoyed the performance.
Go with an open mind and you might find you like it more than you thought you would. Go in there with the attitude of "ewww a play, ugh who would ever pay to watch one of these when I could sit home watching super-bad or internet porn over and over again for free instead" and you will pretty much guarantee you won't like it.
I say go, enjoy it, expand your horizons, don't be so uptight. Really in the end it is up to you.
