If you have a sales tax permit you can apply as a business, or do as was said by Path - buddy up with your local gun dealer. I had an open invite from my gunsmith, but couldn't get away.
With all of that snow..........could you get out TO get away???
95% of the stuff at Shot will be at the NRA.. The only difference is NRA convention will have a lot more people.. families..kids etc... so be prepared to take the days to look as you will be inching your way around crowds.. Both events are a good time.. NRA will be fun as I know that several DR members will be there so I'm looking forward to being able to send them all the corner in person.. LOL
