If it's in a quiet corner of the neighborhood and not "in town", I wouldn't have an issue letting a teenager go by himself as long as I've checked it out myself and approve of the people there (no creeper types, gangs of thugs, etc). A few busybodies with a hair trigger on their 911 machines hanging around is a positive as well
Sometimes moms just need to learn to let go. She's going to be overprotective for his entire life, you're the one who will have to push to let the kids spread their wings.
I'm 36 and my mom still worries constantly. And she does more dangerous stuff than I usually do
