Very true. I meant to mention the 3 mile rule, but I forgot.

Also remember that the size of the field is only half the battle. Trees, power lines, homes etc. are another BIG consideration.

Rookies have a tendency to think any large area would make a good field. Not so. You would think that a Football field would be great, but I recall an event that was held at one once, and it was one of the most difficult fields I've ever flown from (and I was far from a rookie at the time!).
