Fucking hell, wasp stings hurt.
One time when I was around 12 years old, me and a friend were goofing around in the Mojave desert and as I was bopping my way down a foothill, my right foot landed right on top of a nasty big Moiave Green snake's head. It was lucky for me but unlucky for the snake, because as soon as I realized what was happening I crushed it's head. It was pretty wierd watching it's body twist and sway.
Also, when I was around 9, I was poking around under my bed to retrieve something and was astounded to see the underside literally infested with Black Widows... they are pretty common in the High desert... freaked me the hell out.
