I've never been to a gun show and am thinking about going to the one in Louisville tomorrow.
It's time to go... Enjoy.
I'm only looking for a K22 Outdoorsman.
My guess is that you will not find one. I rarely find exactly what I am looking for. BUT... I almost always find something that I'm not looking for, or something that I forgot I was looking for.

Sometimes it is as simple as a set of mint grips that were priced right, or a nickel plated SAT, or a $5 4" cleaning rod, or an owners manual, or an large side plate screw to replace the buggered one in your otherwise mint Registered Mag, or maybe it is just a great bag of spicy beef jerky that you cannot buy anywhere else.

The list goes on and on - you never know what you'll find, but maybe, just maybe, you'll stumble across a table with a red picture box (or burgundy hinged patent box) hidden towards the back, filled with an as new 1933 K-22 Outdoorsman with all the tools and paperwork priced at $1,500...
...Now that would say that you're living right...

NOTE: the above gun was NOT found at a gun show, BUT a person I met at a gun show became a friend and when he ran across a collection, he called me and we purchased some very nice stuff - this Outdoorsman included - and it all started at a gun show...
Enjoy the hunt, for it truly is the hunt that is the most fun. Take tons of time (and Benjamin Franklins) and ask lots of questions. Gun shows are a great place to learn and make new friends.
Let us know what you find.
