If you have railroads, along the rr edges are a lot of bushy areas and bunnies love brushy areas.
Just walk on the rr track and keep looking.
Early in the morning just before daylight is a good time.
If you see one and it runs just whistle about 5 seconds it usably makes them stop.
If not just stay still, in a little bit they will circle back to where they started.
Some of the best rabbit hunting I have ever had is along rr tracks.
And cotton tail rabbits are the best eating rabbits.
Good Luck.
