Gun shows can be a hit or miss scenario. Some are run very well, and others, not so much. I used to go to many, but for the last 10 yrs. or so, I've pretty much given up on them.
Prices have gotten crazy (for the most part) and you see more and more non-firearm items being hawked. Some shows try and charge you $5.00 or more to park your car.
I get tired of trying to get around baby strollers, small kids running around like it's a playground, and teen-agers showing up to show off their latest, greatest fashion trends.
Besides, I have pretty much what I want in my firearms collection. If I want / need something new, I look for it on-line.
