Here's the comment - davidjoaquin said: Levi Blackwolf! great photo of him This is the first time this has happened for me with a photo that I uploaded to Flickr. Neat-o! Also I thoroughly enjoyed their attire and their horses and mules.
Here's what I found out about the group he's in, at least it's my best guess at getting it correct based on the PDF of the 2016 list of entries I found and finding the last group I photographed with a sign in front of it and the last photo I've posted below:
H-13a Happy Canyon Chiefs of the Confederated Tribes of the Umatilla Indian Reservation
H-13b Royal Court of the Happy Canyon Indian Pageant (2)
H-13c Happy Canyon Board of Directors (wagon)
Several more photos--let me know if you know if I'm right or wrong on the group ID, please. Thanks!
Based on the brand on the wagon, I believe I've got it right about these photos being of the Happy Canyon Chiefs of the Confederated Tribes of the Umatilla Indian Reservation.
This one appeared on the list right after the Happy Canyon groups as Park Bureau Scooper.
