Lighted kites. I think these lovely little lights may work well for what we are doing. At 475 linens per foot they would be extremely bright. Make a removable set of lights on a battery box and you have made something that for all perposes would light up the sky and the ground.

Sorry any and all typoes my phone is not cooperating with me today.
