FIRST Double Hang in PNW?

Hey guys! Recently we competed at the CWU District play in the PNW district. We finally got our climbing working and were able to climb with 4450 on the same alliance. We think that we participated in the first double hang in PNW. Is this true? Has there been another instance? Thank you!
(Photo creds 4450 Twitter). Also, thanks to 4450 and 2147!

I thought there was one at GTRE, i could be wrong. It was amazing to see this though! Great job!
