The Secret to a Great Margarita

I was over at friends house last night, enjoying some yummy beef fajitas and he made some of the best margaritas ever. I didn't ask his proportions (and I should have), but he revealed his secret-half margarita mix and half limeade. It really made for the sweet and sour combo for the drink. Note to self-I'm going to have to try this in the blender come summer!
