Having spent the majority of my life in the country I guess I can't say what's normal or not normal in a suburban area...but most places I've lived if I was to see the pic attached in the initial post I'd wander over to see the kill and offer to help. Last weekend I had 3 hanging up outside off of a gantry I built specifically for that purpose. My neighbor promptly jumped on his ATV and rode over to shoot the breeze about hunting prospects.
When I was in school 20 years ago it was VERY common for us boys (and some girls) to have firearms in our trucks...in cases, unloaded, but still. We'd head for the fields/woods after school and/or come straight to school in the morning from the timber.
My son and daughter will not be able to experience that, even though the size of school they go to isn't much bigger than the one I graduated from. Unfortunately the 'public opinion' and issues that have nothing to do with me or people that live where I do still prevail and cause laws/rules to be implemented that have no reason to exist here. It's a sad state of affairs but I can't see a resolution to it.
