I agree with Mandy. Sit down with your FH and talk about the different theme ideas. My FH is the same way and says he doesn't care and blah blah blah, but once I sit him down and we start looking at stuff, he's usually into it and very helpful. As far as wanted to incorporate all those things about your FH, the football, construction, etc.... I would say maybe if you are having a groom's cake, you could decorate it with those things.

I think the western theme would be cute too and there are lots of stuff out there for western theme wedding. I also agree that your dress should be a dress that you absolutely love, that doesn't mean it has to be a "western dress" at all. Whatever dress makes you feel beautiful on your big day.
