Sadly, if goose hunting is your forte', you won't be happy here-especially in Jacksonville. Yes, we have a resident Canada season but those opportunities are becoming thin. Only migratory hunt-able birds are in the NE section (NE hunt zone) of our state, the season is late and very short, and you have to obtain a permit for that area.
As for property (acreage), it varies depending on lots of things. Fields from 2500-4000K/ac. But you won't find any goose fields as they just aren't here like they were back in 70's and 80's.
If you're military, look at your other options. We are not the waterfowl mecca of the Atlantic flyway by any means . . .
