Should I elope and break a promise I made to my dad?

Well my fiance and I have been engaged for three years. Two years ago (at the age of nine-teen) I moved with my fiance from California to Illinois and promised my dad I'd get married in California. I think he just didn't want me to "runaway and get married". The problem is I don't want anyone at my wedding ( i know i need a witness). I think it would be most romantic if it were just him and I exchanging vows. I know if I go to California all my friends and family would want to come and i don't even want just a few. I don't believe it was a fair promise to have to make. shouldn't i be able to get married anywhere in the world i chose? After all it is my day!!!???!?!?
