I'd say it is.
When it was in Dallas, I stubbed my little toe against a bookcase the morning of the convention. Sprained it badly (maybe broke it, I don't know) and peeled a good bit of skin off it. I went ahead and put my sock and shoe on and left the house. After I got to the convention, I was on my feet for maybe 8 hours or so going through the exhibit area--I never got a chance to sit down.
Talked to Jerry Miculek, Kim Rhode, Dr. Ken Oehler, Craig Boddington, Lynn Thompson, Randi Rogers and others. Saw Max Michel Jr., Lena Miculek, Steve Hornady, Buck Taylor, Hickok45 & son, a number of NRA staff and others. I was allowed to hold and dryfire a Korth revolver. I had the opportunity to try out the MantisX training system. Saw a LOT of neat stuff and talked to a lot of regular folks who were working the exhibits or who were there to see the show like I was. Got some free samples & SWAG and even bought a few things.
When I got home, I had to soak my sock to take it off because the blood had soaked it, dried and stuck it to my toe and foot. It was well worth it!
