I have never really been able to explain just why really. It is just a Texan thing, I guess. Or maybe it is because I have a strong historical background with Texas. First my great (x a few) grandfather was part of the fight for Texas Independence. (Here is another link about him!) I have other ancestors that had a mark on Texas. Then I was born on Sam Houston's Birthday and Texas Independence day. And, my parents made sure that we knew Texas History. We would take day trips or overnights all over Texas. One because it was all the vacation we could afford back then but two because I think they took great pride in our history as well.
This song by George Strait is great and in my opinion is a great song about Texas. This slideshow someone put together to go with the song is great too! I got goosebumps when I watched it and I already get choked up when I hear the song.
