The Best Easy Margarita

I've had friends say that they can't tell the difference between this and a real margarita! I made up this recipe myself one day when I was preparing for camping at a music festival. I needed lots of booze, preferably refreshing. And this is the awesome result. I think you could make this into a frozen margarita by putting it in the freezer then blending it, but I like them much more on ice. **Note** This is VERY STRONG. If you want to make it less strong, add another 1/2 qt limeade. Any more diminishes the flavor. I recommend using Newman's Own Limeade. Also, I don't recommend using crappy tequila, use only what you would drink straight.
