Rainbow Air are pleasant and their newer 172s are cool except for missing the wheel cover thingies, which makes 5 knots of a difference in cruise I think?
Flight following around there is great until you slip up. I had a "Say again?" answered with "<sigh> Frequency change approved, squawk VFR, GOOOOOD BYE". I'm sure that wasn't what he said the first time
I tihnk they recognise callsigns of frequent offenders so their patience is already worn thin before you even take to the skies, that's one trouble with renting from popular outfits for out-of-towners!
