Once I mistakenly went to a secure gate at Davis-Monthan AFB-I was lost-and I was a little worried because there were 8 or 9 guards standing there, all with M16s and sidearms, as well as a pretty cute K9 airwoman. I had 2 VERY LARGE boxes in the back of my truck because I was making a couple of deliveries. I had my Sig in a holster sitting on the seat next to me.
I pulled up to the guard, told him I was lost, and asked if he could help. He directed me to where I needed to go (a scant 1/2 mile away), and before he directed me to turn around at the guard house he asked, "Is that a Sig?"
"Yes, it is" I replied.
"Nice gun" said the guard and waved me on.
It's been my experience that not all LEOs and persons of authority are jackasses about weapons.
It's also been my experience that you can't always trust Microsoft Streets and Trips software, even if you religiously get the updates. I've had it direct me onto streets or roads that I had NO business whatsoever being on to get to my destination. I learned a long time ago to print a map of the address I'm going to because at least the maps are never wrong.
