 Do you do a lot of rural areas? Oh, absolutely. Like farms and things like that? Oh, yeah. I didn't see where that would be busy. Yeah, I was just in Fertile on Thursday, installed three systems for a shop, the house, and their lake cabin. So it's been busy there. But not only do I just do municipal water, but water in the lakes area. I mean, there is arsenic in the lakes area. There are the rotten egg smell, hydrogen sulfide. Oh, yeah. Arsenic?
