It really isn't any different to be inside during the summer heat in Texas than it is to be inside during a wintry blizzard or cold below zero in the North. Through the window, it just looks like you would enjoy being out there...until you open the door!
There is plenty of space inside and enough patience to go around most of the time. Towards the afternoon you can start to feel the excitement mounting up because they are ready to run and play for all they are worth. We are catching a lot more sunsets and sunrises these days.
