Thanks for apologizing but I was not referring to you. We'd all like to think most parents and camp leaders are responsible, but it's the people they're with that will screw this up for everyone else and "accidents" happen. I prefer prevention over accidents, because so many accidents aren't accidents, I don't care what they say.
I have seen so many out of control kids and parents or adults that allow this crap when using frisbees, dogs not on a leash, nerf shooters, pellet guns, even horseshoes and croquet and all other forms of equipment than can be used beyond its intended purpose. Then when you ask them to stop even when they have caused something, it's like you called them a name. What inconsiderate idiots they are.
Since it hadn't been mentioned I wanted to put in my ten cents for everyone to think first, act second. There's certainly enough careless people around that would make this not fun for everyone else.
Again, thanks for your thoughts, but I hope you pick up after yourselves so that no one else has to live amongst the ants or other wildlife that this food can attract.
As for your design I think it would look better if you used a 45 degree elbow (not 90) for the one on the bottom and maybe shorten that next piece to 2". This gives the rear handle a slight slope backwards.
