Oddly, many moons ago, a buddy and I were going mushroom hunting and had our handguns in cases tied to our bikes, but were wearing our holsters. The chief of police saw us at the gas station and told us we were breaking the law. He said it was a fine line, but due to the fact that we were in the open, handguns in a case were concealed weapons and we actually should have them in the holsters. He wasn't sure how we should handle it, and told us that a gungho cop could give us a hard time. He didn't really know what to tell us as far as legality went, so he advised us to take a truck instead of our bikes. Go figure.
