I personally think this would be fun, could be very positive if organized and handled correctly...and if done at the right place and time. Though every single one of us has no issue following the law and exercising our rights within the law, it's all about the public perception of how we define it that matters.
Now, my thoughts are, if we were to do this, let's start small. How about contacting Cabela's and see if we can set up a table or something out near the front entrance? At least the crowd that frequents that store will be at least somewhat familiar with the concept of gun ownership. Maybe sell popcorn or something and donate the proceeds to a local charity. At the same time, we could be openly, responsibly carrying and possibly hand out pamphlets or flyers stating the true facts about current gun legislation versus what the main stream media has been spouting lately. A side benefit would be that there are likely many CHP holders and gun owners in general going in and out of the store that our not familiar with our forum and we would likely gain membership.
If this goes successful, and I am sure it will, we could then maybe talk with a local Wal-Mart or the like and repeat the event. Hopefully, the long term goal would be to set up our gathering in a more open, public place.
Just some thoughts...
