I hear you, Jer, but I just can't afford *another* incredibly expensive
pass-time!

Not as expensive as you might think. I paid less than $7000 for my
flying, in-annual (actually condition inspection), all-metal (can be
tied down outside, no hangar necessary) single seat glider. Insurance
is less than $500/year. Annual maintenance is less than $100/year,
though it does include a weekend of my time a year.

BTW, your kids can solo a glider at 14.

Since you have an airplane, you can choose any glider operation within
reasonable reach, and use the plane to get to the glider.
