So this story ends well.
When I arrived at the community college, I found a 110V outlet in back, got permission to charge there, and charged all day @ 3 mph (almost pointless...but free miles nonetheless!) I'll continue to do this tomorrow and Thursday.
I also called the RV park (my original charging destination), got ahold of the right person, and received permission to charge there despite the place being closed due to flooding. I was told there was a pole next to the campground sign that had a 50A outlet on it. When I arrived at the end of the day, I checked the pole--they were either 110V or 30A outlets! (I don't have a NEMA 14-30 adapter). The place was closing in 8 minutes, so I asked around and received permission to just drive past the barricades, pull into a spot, and hook up to a 50A spot. I did so, then walked to my hotel about a mile away, and now I'm happily gobbling down 32 mph. I'll head back in a few hours when full. Best part? The campground host said the electrons were free of charge! So now I have 3 sources of free charging around here. What other car can you drive where people give you free gas (other than a Roadster, Leaf, Volt, etc.)? Awesome.
