Frank,
Sorry 'bout the good natured ribbin'! /ubbthreads/images/graemlins/smile.gif
Really though I would think you'd actually be interested in shootting Prairie dogs, in Montana.
Gophers are small and don't come up to be shot at often.
Is there a particular reason you want to go to Montana?
Another site is having a gathering in April, in eastern Ore., to shoot sage rats (a smaller cousin of the P-dog), and it is open to any and all who would like to attend.
If you have your heart set, or your schedule, and you are definitely going to Montana, I would post on this board (and others) that you are headed that way, and need someone to hunt with.
Getting permission to shoot diggers of all types is usually not going to be hard, and P-dog towns are easy to spot (even going down the freeway at 90mph). So finding targets shouldn't be hard even if you end up searching for them on public lands.
Now that the fun is over, and we stopped teasin' you... maybe some guys from Montana will seriously join in here, and share the wealth of knowledge.
