Congrats to you and your lady. A kilted wedding would be a grand site if you can work out the details. I would point out another consideration if I may. Since you only live 2 hours west of me you may already have thought of this. October is the month in Texas where the weather changes from hot and humid in the first half of the month to more frequent cool fronts with more moderate temps in the second half. For an outside wedding, timing can be the difference between a sauna and a more enjoyable experience. The closer you get to November the better outdoor weather your most likely to experience. All the best.
