To everyone else, thanks for the input. The intent of my first message was to gain an idea of where people fly when they don't have a club or field near them.
In case you missed the point the answer to your question depends on if you already know how to fly in the first place
While kselcher's comments may be a bit overly dramatic the possibly however slight does exist.
P.S. After over 20 years flying I personally won't fly any large (glow or electric) planes in a public park or school yard on the off chance kselcher's scenerio might come true[X(]
Here's a little quiz for you (or any of the math wizs out there) How long (in seconds) does it take a plane flying at 50mph to travel 200 yards?
50mph is well within the speed range of a .40 sized glow trainer (Most common type used for learning)
