Mauser,

If it's going to be wet, getting busted is actually quite limited. The ground is soft and quiet, so just be sure to get into position well before astronomical twilight (about 1hr before sunrise), and you'll be fine.

Although turkeys see great, they lack a large number of rods in their eyes, so their night vision is actually quite awful. They won't know the difference between you and a deer, especially that early...
