I'm Tara Kirschner. I shoot photos all over the world, and I've been blown away by what I've seen so far on my first trip to Texas. I've paddled canyons, hiked through history, and photographed stars in one of the darkest skies in the country. After two incredible days, I decide to head down to Corpus Christi. But before I do, I want to make a quick stop in the charming little town of Marathon and check out its iconic attraction, the Gage Hotel. The Gage Hotel is very West Texas. Built in 1927 by local ranching tycoon Alfred Gage, who owned half a million acres of prime grazing land. You can really tell that it's been there since the 1920s. There's a lot of history on the walls. I feel like I'm stepping into a movie. Oh wow, this is cool. Marathon and the surrounding area are rich in art and culture. And I found the same spirit at the Gage Hotel. like this art installation I found just outside, where even the smallest details tell a bigger story. It's the kind of place I'd love to shoot. I could have just stayed there all day taking pictures. I'm ready to eat, so I head over to the V6 coffee shop and order the migas. Thank you. You're welcome. They're the migas. Enjoy. A local specialty with eggs, cheese, pico, and tortilla, all mixed together. Tex-Mex food is my jam. Literally, put anything in a tortilla and I'm happy. How was everything? It was amazing, thank you so much. Yeah, migas are very popular here. I bet. Are you from here? Yes. Oh, wow. Born and raised, yes we are. Wow. One of the things I noticed is that the art scene here is unreal. Has it always been like that? I feel like it recently just kind of took over, kind of here, Alpine, Marfa area. I'm obsessed. I walk like three feet and take a photo, and three more feet and take a photo. Awesome. Well, thank you for coming. Thank you. And safe travels to Corpus. Thank you. My next stop, Corpus Christi. My adventure here starts at sunrise. Here on Padre Island, I'm meeting January from Horse House. And we're about to go ride horses on the beach.
