On an actual note, one gym I used to train in would leave the back door slightly open for air to get in. One night while training back I glanced into the mirror and saw a pink tail over by the low pully row. I thought it was a rat and went over. POSSUM! For those who do'nt know they can be very BIG! and AGGRESSIVE! I told the front desk guy and he thought I was bulshitt'n. He goes back and then the thing starts hissing and foaming at the mouth. long story short he was too scared to get the damn thing so he got a trash can and we dumped it over,slid a seat cover underneath and threw it out side. I fininsh working out and look outside and this asshole is poking it with a stick. I wish it would have bit his ass.
