I got a good deal on a WM Antelope for my wife and I a couple years ago from Eastern Mountain Sports. That's still the only place I've seen them on sale.

It's a great bag, and worlds above the MH 20 degree bag I had.

I got one of Kevin T's Draft Dodger quilts made by Enlightened Equipment last week and have one night under it so far. I'm gonna love that for warmer weather.
