[CMAS] 16" mirror near complete, Foss Hill

[Colin Caissie]

You're just trying to get me out to Oregon?  Love to.  Hood is on my list.
I could see it from Camp Muir @ 11,000' on Rainier back in 2023.

If you give me the model of your "Pontiac", and the scope.... a mount would
not be a problem.  Probably limited to less than 16".....High power binos
would be my idea....
