Miscellaneous resources
PilotShareTheRide.com My buddy, Baldy Ivy, has put together a terrific free website where you can hitch a ride with another pilot, find expense-sharing pilots and passengers, seek mentors, safety pilots for IFR practice, and much more. It’s a great place for meeting other pilots to share flying and expenses.
Doug Stewart Flight Instruction, Inc. If you're one of the many instrument-rated pilots who craves more actual IFR experience, join Master Instructor Doug Stewart on one of his IFR New England trips.
