Full moon bat tour

We will meet at Texas rowing center at 630 pm and after getting to know each other a bit, we will jump in our boats (kayaks or SUPs) and we will then head to congress bridge to catch the bats and the sunset. And we will head back by 830 pm.
Please bring a flash light, if you can.
(You pay only for one hour and the second hour you get for free, for joining the tour)
Thanks
