Unless I missed it,
@Marie13 's instructor/guide has not been named. Is that intentional? Is it someone we know from SB? Do tell, unless it's a matter of national security, of course.
As for air temperatures, that cold spell last December that Marie heard about was smack in the middle of my Cave 1 course. It was 28F one morning when I loaded the truck. But last week I was able to enjoy days in the low-80Fs. Too warm for Marie, but I sure prefer it. North Florida winter can be unpredictable.
Glad you're managing to enjoy it, Marie.
