I know there is a restaraunt called Moe's at the intersection of Clyde Morris Blvd and Herbert Street that has WiFi. I am sure there are others and if you contact Wayne (GL1800GSXR) or Tom (Silver Meteor) they would know better. If you can't find one, come to my house.
Check with the FBO at the airport. Most now offer Wi-Fi for flight planning purposes, although, you would probably have to be fairly close to the router in order to pick up a decent signal. Where the camping area is in relation to everything else, I doubt you will pick up a wi-fi signal.
