Second Breakfast? Hmmm...I don't know. We met the group with the nun just about a 1/2 mile from Trail Crest. I think I smelt bacon!
BTW, this nun was NOT wearing boots or tennis shoes, but wearing the shoes you wear with the habit. Unbelievable and INCREDIBLE!
I am glad I brought a chuckle to some.

I showed my wife this thread and she just busted a gut!

Anyhoooo...back to the topic at hand...where were we? Oh, "Lightning from the Sky...Thunder from the Sea"...Wait! That's a 1st ANGLICO motto. Regression...Quick, out of USMC mode...there...thunder and lightning...
Generally, you see clouds forming during the afternoon after 1:00 p.m. Hence, why my cutoff time is 1:00 p.m.
Beware of "puffy clouds" -- cumulus clouds -- can turn into cumulonimbus -- thunderheads. A lot of convection occurs in Owens Valley.
