Sandusky badly needs a Supercharger! It's coming next year...
If you are going to Catawba Island, there is a McDonald's on the way with a J1772 charger (make sure to turn it on: there is a switch on the right side). I tried it earlier this month and I was getting 30A/206V. Not a supercharger, but might come handy if you just need to add a bit to your range.
