The open floor plan is perfect for the Summer Texas heat and humidity..... and for the wet Thunder storms of spring I just strap a tarp on one side with bungy hooks to block the wind and rain....Like yesterday we had a big rainy thunder storm blow thru...I was so worried about my little 5 week olds....so I put on my slickers and went on out to check on em and they were dry as could be playing in their sand box LOL...lil buggers
