Areas to practice
You can practice putting in a lot of different area's. You don't need a basket all you need is a pole of some sort or something that is around 50" high.
As far as driving practice goes that's a bit more limited but not to hard to find. Most outdoor sport fields work great, especially football fields. Their good to help mark your shots with the yard marks.
1 yard = 3 feet.
Farm fields or open parks are good to.
