BTW I have implemented a 3 drink cap on these. Not many good things happen after 10oz of Tequila, trust me on that. :-)
I hear you on the limes. They make all the difference. Whenever I go to FL or down south the limes there are so much better I wish we could get the good stuff up here but, it is all the cheap imports and greenhouse variety. But, I know what you are talking about and those set the drink on another level.
