I live in a rural town in Maine, and I usually pay as follows for decent bud, what I assume everyone refers to as mids.

1 g- $10
1/8-$25-30
1/4-$45-60
1/2-$70-90
1 OZ.- $100-$230

Granted, I've never smoked weed that wasn't from this area. Highs run about $40 an 1/8. I've been told the average weed up here is pretty good, but I have no real frame of reference.
