Madts, cypress was actually my first thought, but the janka hardness on it is 550, WAY too soft for a door that is going to be banged around. Eastern Red Cedar has a janka of 990, which is why I thought of it.
For whatever reason, furniture grade hardwood is really hard to to come by here in North Alabama. I managed to set up an account with United Plywood, but the local branch manager is such an arrogant prig I do my best to avoid doing business with them. My preferred source for lumber is a local guy who saws local logs. The only down side is that limits my selection pretty sharply. I don’t know for sure that I could get juniper.
Because of my supplier my wood choices are pretty much limited to red oak, hickory, eastern red cedar, cherry, walnut, sassafras, poplar, and maple. Sometimes he has red elm, white oak, and a few others, but not very often. I really wish I had a broader selection to work with, but not that many people seem to be woodworking any more. :-(
