FIRST check your state law. Call the state police and ask for a read. Or state attorney... don't check with locals until you've covered the state law. Then determine if there's local ordinances that read contrary to state.
Once determined then check with locals.
For us Virginians for instance, and as I understand it - local gun bans were pre-empted on July 1, 2004 - BUT open carry has been around for ever - almost. Here, CHP does not affect open carry, in fact (July 1) hunters in the field may now conceal weapons during inclement weather without a permit - and carrying a concealed hand gun while walking in the woods DOES NOT constitute hunting. (If this is wrong - I just know I'll be corrected shortly.)
The reason for checking with state first is that we've found local officers are not yet up to the new law changes... it'll take a while before all settles down with their training.
In other words - find out what the prevailing read is on state law, then find out whether there's local banning or not, and if the officers are aware of the new law(s). A few phone calls should do it (but if you run into a "Hell no!" - double - triple - check with other sources.
Hope this helps.
