Well, mine is fairly obvious, I suppose. It's just my name. Not all that creative.
Although if I had to pick something that wasn't my name, I'd probably go with something like Montalaskan as I'm a Montanan who is madly in love with Alaska.
Although having 3-7-77 in there somewhere is tempting, too. Because in Montana, if you saw those numbers, you knew someone was going to hang. Hehehe.
