Something similar happend to my friend at SFoG. We are walking to the exit of the park, as it is about to close. Well, we cross right under their chair/ski lift ride, and guess what happens. My friend stops us and is like "Guys, look at my shirt."
Well, somebody spit what looked to be tobacco onto his shirt from up above. He wasn't very happy.
I swear it was not me.
I never spit off the rides.
I would never think of you, even though I really don't know you, to be the type to do that. People on forums like these generally have better things to do, and are a little more intelligent than whoever did it.
