Another misconception about flying in the USA, plenty weather over there, infact I've encountered far more severe weather flying in the States than anywhere else in Europe and believe me I've been around. Plenty busy ATC too if thats what you really want.
No doubt this will generate another ten pages from the usual pprune armchair experts who have probably never flown an aircraft let alone been to the States.
Ladies, Gentlemen, I leave you to continue....
