I thoroughly enjoyed it! A great atmosphere with a lot of people that enjoy the hobby. And, if you go on the last day, opportunity to purchase (at a discount) the demo gear that the vendors don't want to haul back with them.
Don't get me wrong, there is a LOT of snake oil and smoke and mirrors, just smile and go on your way when you meet or speak to these bozos.
However, they announced at the end of this year's RMAF that it will move to a new venue next year. And, when I was there, the current venue was under renovation. So, I really can't tell you much about the venue(s) past or future.
For many years, I would go to Denver for Great American Beer Fest! That year, I decided to go to RMAF instead. These are typically held around the same time, and they have also been held on the same weekend before.
We have friends in Colorado, so typically make it up there once every year or so. I will often plan to make it to at least 1 of these events while we are there.
