Just finished a trip from Florida to Nevada and back.
About 50 hrs there and back.Total trip 4000+ miles.8 days.
Absolutely stunning scenery from Texas on west.
Not for the faint of heart or inexperienced though.
We filed everything IFR.Got about 7 hrs actual.But a lot of legs were 4+ hrs above solid overcast at 12000 feet.
If you're low hours take an instrument instructor with you.
Mountain weather can be kind of treacherous.We where nearly caught out a couple of times.On long trips like this things can get out of hand kinda quickly if you're not sure about what you're doing.
When in doubt take an instructor with you...
Fly safe
