We had been to Swan Lake in the past with small children on several occasions, but I didn't remember this particular shelter area. The view is beautiful, even on a cold, windy, and not-very-green day (last Friday). I'm guessing it's MUCH more scenic with the trees and grass/flowers in full spring mode at the end of May (but I still thought it was a really beautiful setting for a wedding!)
This is the garage-looking restroom area, located not far from the shelter house.
This is inside the shelter itself, and if worst comes to worst, you could sit inside the shelter at the picnic tables and watch the wedding from there!
