Please be sure to post plans somewhere as you guys refine your designs. I'd love to be able to do as you say, Rob, have that door shut at a certain time (now that daylight savings time is over, 5 pm would work great, of course, that would have to be adjusted after New Years and the return of the light). I'm not so concerned with opening it, although that would be cool, too!
