Wagon wheel and bungee cords! Perhap you won't make it! It is June 25-27. Leave the car at home, grab the future Cobra wife and come on up any ways. Heck you are not that far! Besides, you may get some great ideas that you will want to use to finish it out.
By the way, you are getting engaged next month? So does that mean you have an engagement to get engaged? Sounds like a Dilbert pre-meeting meeting to me!
Do what I did. Get drunk on the beach and pop the question. More fun in my opinion.
Word of advise (like mine is worth anything!), your comment about the leash. There is a saying that goes something like "a man marries a women expecting her to never change and a women marries a man expecting to change him'. RUN away from those types. Cop a 'if you don't like me the way I am then $*&^ off' attitude and expose her to all your bad habits (beeee yourself), before the engagement. If she doesn't complain and she sticks around, you may have a keeper!
