Claudia, I tried Glacier a number of years back and wasn't too impressed by it, thought I might as well buy tomatoes in the store...
Although I don't have Bloody Butcher this year I've grown it several times and it was always the earliest to ripen for me, ahead of 4th of July. It's OP, with tomatoes about the size of a ping-pong ball, and quite flavorful. (hope I'm not repeating myself here, I know I mentioned this recently but pretty sure it was a different thread)
