Texas Rendezvous. You should look it up, I really liked the event. I went to the third one which was located in Plano, Texas.
Fingerboards are used to replicate skateboarding maneuvers using one's hand and, quite obviously, fingers. The number one source of 'fingerboarding' products is the company 'FlatFace.'
I will not recommend them, only fun for collecting. If you want to start fingerboarding you should go with a tech deck, they are much better. Then you should get a wooden fingerboard, bearing wheels and some better trucks.
Well, I don't think many people make miniature shopping trolleys but there are some good sites to get other good obstacles like http://flatfacefingerboards.com/ or http://blackriver-ramps.com/.
You can use three fingers but it is harder to do tricks and you are supposed to fingerboard with 2 fingers as a skateboarder would use 2 legs.
