Here in Texas, Summer's can be brutal. I'm use to the heat and work in it a good part of the day. Having a sun shield would be nice for my grass runway. So I am in thinking mode for a portable sun shield. It would be on wheels and used for runway, primary and firewood splitting, equipment repair n servicing secondary. It would have to have some anchor points for those stormy days we have. It may be a good winter project. BTW, I forgot to mention my runway is 60x300'.
