Just took my 727-100 from KDCA to KIAH on VATSIM for another awesome flight.  I flew over a rather large thunderstorm over Tennessee and Arkansas, and there was quite the lighting show.  I flew the entire DAISETTA8 STAR to IAH (thanks to Navigraph chart software), but no APP or CTR was online, so I had to manually vector myself to the DUCOZ IAP for runway 15R.  Everyone who isn't navigating this aircraft the old school way is really missing out on a fun learning experience.  I am going to take the MD-11F for a spin tonight (FedEx Virtual Cargo) so I can enjoy some "easy" navigation for a change.
