I was taught the Oath because my father, who was my instructor, believed it to be the best thing in case I do ever go out of state, or even out of country. I believe it should be taught none the less. Besides, you have to know it to get your C Certificate last I heard.
When I visited the Masonic Lodge in Ruidoso, NM, I had to recite it. I memorized it in about 10 minutes before I left the cabin, but there were slight variations in theirs. They were still impressed that I could do it from memory. Sad thing is they had cards for people to read from if they didn't know it :/
