A few other quick questions:

1) Sorry - can you define 'flat'?
I've learned that 'flat' is relative compared to where you live - I grew up in the lower Catskills in NY with real hills, whereas a 50 ft incline in SW Michigan is considered by most as a 'hill'..

2) Any water?
3) In that pic, where exactly do the birds roost?
4) What is the general travel direction from the roost?
5) Do you set up in different locations, or always the same spot?

I'm assuming the birds fly down and immediately head to those fields to strut & dust?
