Glad you had a good time! Son and Father in law sounds like a good hunt.
Think I met Ron 25 years ago and he's a GSP snob all the way.
I do remind him however we've got his 35 minutes in downing 6 birds beat by the 23 minute time with my deceased Lab. Not that it's a race.
IF I were going to make Preserve Hunting a staple activity (which many do particularly with kids and parents) I'd probably opt for the Pointer. Aside the point being a beautiful thing it's easier to hunt over, adds some training nuance and Preserve birds are often too easily 'caught' by a hard flushing dog.
That leaves the waterfowl issue though and the limited choices you have in Ohio winters and pretty cold water. Dogs like Drahts are probably the best bet...something with a coat.
