I started out in power and then went to gliders.  I still fly both.  My first flight was in a C152.  It was a perfect day, clear, warm and sunny, no terbolence.  Lately the weathers been crappy.  My first glider flight was in a 2-33.  It was a decent day, and I remember being intimidated by not having an engine.  The one thing I love about powered flight is, that if you mess up your landing you can always go around!
