Mel's growing mix (not soil!) calls for 1/3 each of Vermiculite, Peat, & Compost.
So, I'm tracking it all down! Called Northern Gardens in Cody. They have Vermiculite for $34.95 for a 3 cu' bag.

Ok... been making lots of phone calls. I saw an ad in our local paper for the Big Horn Co-op. Well of course.... they supply all the seed for our local farmers... we are a farming community.
The great news is that they have Vermiculite for $26.29 for 4 cu'! Awesome! That sure beats $35 for 3.5 cu'!

Mel's Square Foot Garden website. They have a very helpful forum there. One of the SFG forum members posted this youtube video of her garden:
