Fuz, got the same law here in Ohio. First year of deer season I too used a dowell rod. All of the gun stores sold out quick. Afterwards, the stores re-stocked and I bought a plastic rod for my 870. But, I swear during gun season it doesn't sound (gun fire) like too many hunters fixed their shotgun with the plug. It's a lot cheaper to buy a plastic rod compared to your gun getting impounded, etc.
