RB...Biker Rally=alcohol+herb or whatever substance of choice????? and you want to add firearms?
I would stow my rig in a saddlebag or a lockable compartment if you have one once I got to the rally (or better just outside of town.)
I want to say that IMO most everyone there would be carring some kind of weapon, but that sounds too much like profiling....so I won't say it.
Maybe it is a different kind of biker rally? Christian Harley Riders of America? It could happen.
http://www.junebugboogie.com/ If this is the one, Cookville folks need to answer your question. Some TN counties are a little harder on carry than others. At least TN recognizes most other state carry permits.
I guess I would need more info about JuneBugBoogie to decide whether to carry or not.
