I'll offer a sincere reply as this thread hurls towards an inevitable lockdown.
Yes, there are occasions whereby I feel less safe because someone has a firearm in the woods. I log about 5,000 mountain bike miles every year on the singletrack trails in our national forest right outside town. Several times a year, I'll hear gun fire at a very, very close range. In most cases, it is someone from Phoenix up here for the weekend. They drive into the trees for five minutes and think they're in the middle of nowhere, when the reality is, they're often damn close to houses, trails, summer camps, or even a city park. While they usually (not always) have a reasonably good backstop, they often don't know on the other side of the hill is a popular trail. I can tell you, when I hear gunfire in close proximity, but don't know from where it is coming, or the where the bullets are going, it sucks. And it happens with alarming regularity.
I also have acquaintances who carry that I can't say I trust with that responsibility. Nice as they are, I would rather they not be in my presence with the tools to stop a heartbeat.
