Whats a "usual" night of road cruising? 1 snake, 2 3 I dont know what to expect I've never seen more than 1 road crusing but maybe its the location
I don't consider a road productive if I don't see 2-3 snakes per hour. There are some areas I have road cruised where you can see 20 snakes an hour (although diversity is low), and others where you hope for a snake a night (but these are areas where you look for a target species).
During the morning hours, frankly I consider it good if you see a snake or two.
As for habitats, I find that roads that go between two habitats can be more productive (along the edge of a forest near a field, for example). Roads through the middle of a relatively uniform habitat (be it desert or orange grove) aren't as productive.
In FL, I would usually be looking for a road that ran along a marshy area or at least between some sort of canal/creek and a patch of good habitat.
