We should put a sign on the garbage cans near hole 1:
For more cans and bottles, please walk the course
Seems like the average bottle stays in the garbage can for less than 2 hours there. Surprising that nobody gets the ones on the course.
Here's a tip I use, when I bring beer, I keep the bottle cap in my pocket. Then when I finish a beer I put the bottle cap back on and put it back in my bag. This way it doesn't spill and I don't litter. It also makes a handy butt pail.
