In late August I was hiking in Montana on a trail at Spanish Creek, which is also a trail used by those on horseback. Spanish Creek has a public hiking trail, but to reach it, you drive through the beautiful ranch Ted Turner owns where he has bison.
We came on these riders while hiking. I decided to paint them in a large gouache painting. It's not easy to paint a large painting in gouache (well, not easy for me, anyway). This is 20 x 24 inches and I've just blocked in the large areas. Much more work to do.
