Looking forward to hearing & seeing 'stuff' your hunt, Jeff. I think the tip would depend on success or failure, type of hunt- on foot or baited, expertise & ability of the guide to not only get along, but become good friends - his companionship towards you and your son. Being dropped off into a tree stand over a bait bucket is a mite different than an actual guided hunt, stocking, etc.
I've seen tips paid to guides from 0 to a $500.00 being normal and one of a Back Widow Longbow + 1,000 dollars - one tip - imagine that.
