There's a small private lake just outside of Reading. I skied there several times one summer and the folks were very nice. This was several years ago and I no longer have any contact info. They used to be listed as an AWSA club, but I don't recall seeing them listed in recent years.
I lived in the Pittsburgh area all my life until 2 yrs ago. There's 3-4 private sites and used to be 4-5 sites on public water. OH has many more private sites.
rodltg2 made some nice looking decals. You should be able to trace the design and then screen print it. From another shirt 'If you can't ski with the Big Dawgs, stay off the dock"
