It's a small area, and I'll be using my longbow so running and gunning won't be an option.

The gun doesn't scare them our of an area, it's people moving all around. If you know the kid/adult, ask them to just let the other birds in sight wander off before going to the bird.
An Oklahoma guide used to instruct his clients to shoot the last longbeard of a passing flock, and not get out of the blind until the guide came to pick them up. Sometimes they shot two or three toms from the same flock, on as many days.
Many times we've gone into places pounded by hunters on a celebrity hunt and arrowed birds within a few hours.
Just be patient and don't give up. Sometimes the birds will come in silently.
The turkeys will also likely react a little different as the strutting season progresses and the hens start nesting. I'm not sure how long your season is but that is obviously another consideration. If you are hunting private land with a long season you have lots of time. If you are hunting public land with lots of hunting pressure...that is something else to consider. Obviously there are fewer toms available as they are harvested and the season progresses but it may or may not matter in your particular area?
Think of all the birds that get killed on public areas every year.
I need to be honest, though, I have not hunted in New Hampshire, but had consistent success from Florida to Wyoming, and probably 10 states in between.
Not many ranches in New Hampshire, Jims.. :-)
I'd rather leave my bow at home...
