Be aware of this FCC ruling
Had heard it was occurring, but now it is confirmed and hopefully stopped in its tracks. http://www.rvmobileinternet.com/fcc-strongly-rules-that-wifi-blocking-is-prohibited/

Had this happen at a very popular central Oregon coast park. The unsecured WiFi sites I connected to around the park the year before were still there and unsecured but I couldn't connect. My only choice was to pay the park for their WiFi service. Didn't have my smart phone then to try tethering.
