If anyone will be in Northern WI the next two weeks, Blue Vista Farm should still have blueberries. It's easier then humping it into the Quetico for blueberries that actually taste like blueberries. This place is how an orchard should be run. They have fruit crops coming in throughout the late summer and fall, not one crop one short season. They say stuff is running about two weeks behind normal. The blueberries this weekend were $1.75/lb you pick or $2.25/pint already picked (presumably a pint, which would be a pound, I'm getting my info and berries from someone who was there). Web site says they should have raspberries too.
If you like freshcut flowers they have some beautiful gardens and I guess they give you a scissors and let you run wild. Don't know how they're priced. First apples aren't in yet.
