I stopped at a scenic overlook to take some pictures. While there, I started talking to a guy who pulled in next to me. A moment later a woman stopped and we all started talking. Waterton was having a wildflower festival that week. Apparently, Waterton has the largest number of wildflower species in Alberta, and maybe Canada. I don't recall. It is a huge event and draws people from all over.
The woman worked in the park and the guy had driven down from Calgary and was one of the guides taking people out to see the wild flowers. We drove back down the road and he started pointing out flowers.
