I think some people are missing the point. The guy is NOT stealing use of WIFI, he paid the fee to sign up for Flying J internet. As long as he paid the fee to get to log in, it does not matter if he is not parked in a Flying J parking lot or not. You can't use their internet unless you pay, no matter where you park. So I don't see why people are comparing this to illegal use of other peoples system?
By the way, for the person who originally posted. I traveled with my husband for aboug 5 months and we found that Flying J was by far the most reliable of the WiFi systems. The one we found to be the worst, and he has tried them again now, and they still seem to be pretty bad is Siricom that is available at most Pilots. If you are an online gamer, Flying J or TA wifi are the way to go.
Also some of the cell phone companies have wireless pci cards that gives you internet access basically any place that your cell phone would work. And those are awesome. We are getting ready to change back to that method again, it costs about 80 dollars a month, but in our opinion well worth it. Then you can even get online when you are sitting around at customers waiting to load and unload.
