Does anyone know if Anza is happening next year? Thanks
Sadly, the SDO website/meetup pages seem to be inactive.
Jeremy, this isn't what you asked, but SWSW 2022 is definitely happening (also with great desert terrain), 2/19 - 2/27 in Tucson & Phoenix: https://southwestspringweek.com/
I talked to Mark Prior about Anza-Borrego last week. He has a hip injury and isn't in shape to set courses. There doesn't appear to be anyone else to pick up the baton and run with it.
SWSW looks like the best opportunity for desert orienteering in the near future.
