Yes it can be done, I've done it many times, but.....
I hosted such an angler ( supplied all local flies, lodging taken care of, all meals, licenses and ground transportation ) for a 2000 trip to the Sierras and valley rivers and Pyramid Lake Nevada, then I hosted the same angler again in 2002 for a similar trip. On the first trip he caught the Cutthroat of his lifetime and his first King Salmon on a fly. On the second he caught the Rainbow of his lifetime along with a many, many more fish. We still are friends, we still converse often, he hints around a lot about the possibility of his return. It’s 2012 and I’m still waiting?
We named a street out here after him. " One Way ".
Seriously though, other than that one guy who really is a friend, we host anglers here often, but not without knowing substantially more about them than is often revealed through typical internet chat and bulletin board postings.
Look at this way, if you wouldn’t pack up your favorite rod and reel and send it to that person without knowing if it would ever be returned in one piece, why would you invite them into your families home? Or meet up with them for a one on one pack in trip?…..Do I hear dueling banjo’s a playin’ around the campfire
It's one thing to be willing to play host, but it's not all that realistic to expect that life's twists and turns will always allow the other angler to reciprocate.
I'm willing to consider it. TT
