Awright....I'm going upstairs to iron. It's only 99 degrees, sure, why not. Hey! Gunga Din! over here with that water skin if you please!
I want to thank everyone who anted up their two, twenty and 99 cents regarding my photography quandary. Combing through the wisdom I think I've distilled an answer.
It's going to involve my Goodman building me a portable hard wall and some cooperation on the part of the weather but the job will get done and the results will be what I have been looking for.
