First Soaring Experience

Hmm. I know you're kidding, but why wouldn't this be an option?
What's involved with towing gliders -- NOT for hire?

The hard part would be finding an STC'd towhook, or finding a FSDO that
would give you a field approval.

With a notch or two of flaps, you would be plenty slow enough for most
gliders - and if you kept it light on fuel, performance would be fine.
182's with O-470 engines are routinely used for towing.

The training required is pretty trivial - you need dual instruction in
a glider being towed by an aircraft (and it sounds like you already
have that, if your flight was with a CFI-G) and a checkout from another
tow pilot. An hour of flight and an hour of ground is plenty, and can
be used to meet your BFR requirements if the tow pilot is a CFI.

The real issue is insurance.
