Unfortunately some stereotypes exist for a reason... This morning after departing LAS we overhead a GA pilot that launched out of SGU asking about flying over the Grand Canyon to center. The exchange started like this and didn't get much better... "Hey there center, can I just overly the Grand Canyon? I thought it'd be on ma Garmin but it isn't, ain't there some special routes or VFR corridor I can do?" Guess I could've been like that GoJet pilot in the other thread and keyed the mic to say something snarky , but we just shook our heads and listened in amazement at his ignorance and center's patience. Kudos to the controller for being magnanimous. So a little PSA for anyone flying into unfamiliar environs for the first time, do your research first and learn about any applicable rules or special operating aspects. By all means, ask questions as needed but at least be mildly informed for the good of us all.
