There are a lot of reasons why I’m not an outdoor person, but reason #1? Snakes.

I am so terrified of snakes that when my daughter was little, there was a small garden snake in our backyard, and I ran like Usain Bolt. I’m not proud to admit this, but I left my own child in her playhouse to fend for herself. That’s how serious my fear is.

Between mountain lions, bears, and now snakes, that’s more than enough to keep me from camping, or even glamping, all summer long.
