Is this too late in the year for the bats ?
November is the end of the season for the bats, in my limited experience Thanksgiving weekend is not a good time for bat viewing but I'm hoping this year will be good for viewing bats and a UT football game.
I think that most of the bats are gone by now. I don't think you will be able to see the ones that may still be here, it will be dark when they fly. You can call the phone number listed at http://www.batsinaustin.com to get the latest information. I would be interested to know if they are still around. Let us know what you find out.
