Oct 19 Thursday- sunny again today. We stock up for Mexico at the Super Wal-Mart here in Carlsbad. Tonight we go to watch 300-500 thousand bats immerge from Carlsbad cave. It takes anywhere from 20min-90 min for them all to come out. What a sight, they circle counter clockwise before taking off. No pictures were allowed when the bats came out of the cave..
