Because they were not your normal group of people, I obliged them. I gave the best lessons I could with 2 batteries. They were a very captive audience and I had a good time teaching them about all that a P4 can do. They really liked active track. They had me follow a buggy. They got a trill out of it. I've known this group of people for 45 years and made sure I never took their picture face on. My friend took this picture with her phone. I telling my Amish friends how they could get work inspecting all the wind turbines in their area. They don't own computers or have any use for cameras. LOL ? It was fun anyway. I had to make sure I didn't land in horse manure. Those are hitching post I'm standing by.
