I was wondering if DC always has the sloth out when people visit and can you pet it? I used to teach middle school science and fell in love with sloths when I covered biomes. It would be so cool to touch a sloth. It might just make me go ahead and buy the darn tickets for DC. I have always wanted to swim with a dolphin, but not necessarily in December. However, if I get see a sloth, I might just splurge on DC tickets.
