Re: WiFi parking!!
I'll do you one better, or two.
I used to have a yagi on a tripod that I could point at any neighbor's house, this was 20 years ago when nobody had passwords. This gave me access to more than the houses on the adjoining lots.
I used to use the same antenna at work, I'd sit at the edge of the company's property and aim it at the wifi router on the ouside of one of the maintenance buildings. I would receive calls from my coworkers asking what I was going in maintenance and would tell them that "no, i'm not in maintenance, I'm having a smoke on the other side of the railroad siding. If i stand up and wave, you will probably see me."
I've also connected to business wifi networks while sitting in traffic (as a passenger) while being driven through parts of Hawaii.
