I did it once and it was a lot of fun, we flew out over Lake Michigan by Frankfort. It was very cool and since I was a student pilot at the time they let me fly everything but the landing. It was very quiet with just a little wind noise, the views were incredible and the whole experience was great but went very fast.
I did it before in Scotland UK, serenity of flying without any 'engine' noise- peaceful and quite sure you'll enjoy it.
Depend on the 'up-draft' of the day you'll be doing lots of turns to get the glider spiralling upwards, enjoy.
i've soloed gliders and **highly recommend** taking 1, if not more, sailplane flights. once you get comfortable with the various elements of soaring (for some, they're non-issues; for others, they're more :redface: there's nothing quite like it.
have fun, tell us how it went - and post some pics if you take them.
