Just make sure you can see there are no cars nearby if there is not land, if not go for the paddock.
Just remember being on the road you have a better chance of being found if something goes wrong, and also easier to put the plane on the trailer
I landed on a horse track once, was doing powerline checks and was hungry so landed on the racecourse got a pie from the shop down the road and took off again, of course there was no horses around and very few people
Forget where that was, maybe up around Wagga/Coota but really can't rememer the town.
