We get bad storms in Texas too. Two years ago it was raining so had at the Javalina Rally
at the Davis Mountains State Park, TX the park rangers came and knocked on everyone's door to leave everything evacuate because of flash flooding.
We also got caught at Garner State Park, TX by a huge storm while camping during Memorial Day. The park host had a casita
and the water was up to the door. Some RVs had water halfway up the door and some actually floated away down the river. Both places didn't have cell signal. Watch the video on the webpage and you'll see 5th wheels and motor homes.
