We, two of us, have been to Sparks, NV to visit. I have pictures to prove it.
We went to Granilbakken Treetop Adventure Park in Tahoe City. Here are the pictures. I really didn't know what I was getting into. I thought I did, but, turns out, I was looking at the Flying Squirrel course for 4-12 year olds. Ooops.
