RE: Field hunting strategies
There's also a bit of this discussion on GMMAT's thread about "destination = long sits" a couple threads below on the front page...
Ideally, you want to exit through the woods without spooking anything off their feeding pattern, especially if you want to try the same hunt a different night.
Later in the year, I've rattled and/or snort-wheezed to clear them out of the area, though I prefer not to.
