"...its caused by hot air currents"

David, I think you have nailed the cause down LOL!

As for Custer's last stand I recently watched a program where, using the location of recovered cartridges his men fired, they were able to learn that there was no "last stand". By the time the last troopers were killed their lines had broken and they were simply doing the best they could.

Chase asked Steve if us Rebs enjoyed the picture of Custer being wiped out. Now that leaves room for some less than kind remarks. Maybe we better stop here LOL!
