Unless I have missed something, everyone is talking about the procedures they fly. As an ex gliding instructor my main comsideration is "is there a suitable field available". There is a site that shows what crops look like from the air and unless you have extremely good eye-sight is virtually impossible to see how high crops are and the condition of the field until you are vitually on top of them.
I recently did some flying in Maine in the US,the state seems to consist mainly of trees , a few fields, some water and roads. An engine failure there would have been most interesting, as it would be anywhere there was not "a suitable field".
may the force be with you.
