Going to Montana!

I'm leaving for Billings, Montana on 6/19, along with a group of students from my high school to help some nuns in their ministry to Native Americans for a week. We'll also be visiting the Crow reservation and spending a day or two at Yellowstone.

Just wondering if anyone lives in the area, or has traveled there, and has any other tips on what to see and do. Thanks!

(I'm excited about the trip, but will miss the cats like crazy!)

How very interesting! I can't give you any travel pointers, but are you studying about the Crow indians before you go?

If any of the Elders offer you gifts, do not refuse!
I had a very lovely Lakota woman of about 80 years give me a handmade wedding blanket, I tried to politely refuse as I'd been taught, I thought the poor woman would cry, so I took it with many, many thanks.
