So cool! Except for the water (on the ground, I mean, ha ha) that took me back
to my early training days in Cumberland, MD when - for lack of a better idea -
I'd go to the field on similar days, often there to find my instructor (who
lived 3 hours away), insisting I take a tow in similar low-cloudbase,
drizzling, superficially gloomy conditions. Many times we'd find
intermittently usable convective lift, and it wasn't long after I got my
license I figured out I'd been also learning a whole heckuva lot more about
the atmosphere and in-flight judgment, too. (Thanks, Tom!)

Man, it is FUN to soar on "unsoarable" days. It's even more fun to be having &
able to do so when XC!
