Karen, yeah... the different license levels have more access to the bands. Techs are limited to certain areas of several bands..... Generals get wider access and for Extra, everything is open. I don't think power plays into it, just the parts of the band you can legally work.
As far as CW, I hated it then, and have no desire to learn it now. I have heard that for some of the more practiced folks in the art of Morse Code, it becomes more like a language than a code with dots and dashes. Just like we look at a series of letters and don't see the letters, we see a complete word, and moreover, a complete sentence. I've heard the folks who are really adept with code, describe it in that same manner.
I remember going to Norfolk or Virginia Beach to set for my 3rd class radio-telephone back in the 70's.
