Folks, I live in MT (Billings) and want to fly XC to OH (New Phili) where I grew up but have never yet made the trip. I am VFR (850 hrs) and thus am concerned about Wx issues primarily. I have a 182 with a good autopilot etc and have a route already planned, but am most concerned about “when is best to go”. Any opinions or recommendations? Thanks much in advance.
