However if I were out there on a Saturday, I'd know better than to try to practice with the number of people there. Your discs aren't hitting them and getting beaten up. This is good. It doesn't do you a lot of good to be able to throw 500 feet if you can't do so without hitting a tree. Oh boy, let's see.
Most people throw backhand.
This is the normal Frisbee throwing method. If you can't do this, I can't help you. Don't throw the disk higher for more distance. It fights gravity, slowing down, and then at the top of its flight path, comes back to you like a boomerang. Throw it flat and level.
