Here are ten reasons I avoid shelters. I am sure you have many of your own...
1. Sleeping with strangers is creepy
2. Sleeping with mice is disgusting
3. Sleeping with snorers is not sleeping
4. People come and go at different times interrupting your sleep or what you are doing
5. People tend to take up more room than they need
6. Large groups show up when you least expect it and most are whining, spoiled kids
7. People fart at will
8. Thru-hikers often think they are special and you need to make room for them, usually when there ain't none
9. Normally civilized folks in real life, have no manners in shelters
10. People think their dogs are welcome or if they ask, they think people will answer honestly
Do you open your house to just anyone walking by, I don't.
