Thank you for taking the time to respond, theotherlily! Much appreciated.
I see about a dozen plays a year, which is all I'm able to where I live. Soon, I'll be moving to a city with much more theater, so I'll certainly see much more. Outside of my professional reasons for moving, on a personal level it's largely motivated by a desire to be around a more lively theater scene in which I can be involved. I definitely hear you about understanding theatricality vs. storytelling in TV, movies, et al. Though the amount of theater I'm able to see currently is rather limited, I make it a point to read AT LEAST 2 plays a week (great local library system!). I know that isn't totally making up for not seeing much theater, but I'm definitely learning tons from reading.
As far as what I've written, in college I wrote a full-length, and since then I've written another full-length and 2 long one-acts. A Playwright friend has looked at them, and I've gotten good feedback, assured that I'm ready to be produced. I have been reticent to send my plays out, but am planning to do so soon. Self-production is something I've thought about and hopefully will be able to pursue when in a more theater friendly place.
I don't plan on applying to MFAs this fall, as I know I've got a ways to go before I feel ready. My interest in the programs listed is based on aesthetic interest with the professors and my limited understanding of costs. Anyway, thanks for all the info you gave, you gave me tons to think about!
