Thanks so much for your entries. Here's where we are with feedback on them:
#12, #10, #16: Although I personally like the link concept, no one in my feedback group likes it as much as I do. We probably won't go with this design. #5, #6: I like this design but the H looks a little too much like the H for the Hilton hotels. Still, this is our favorite of the batch. It's simple and clean. #11: Although we like the H as a possible stand-alone image on a T-shirt or something, the green portion reminds me of bull's horns. We're close to Texas here, which could confuse people.
Please keep the entries coming. We're looking forward to picking a final soon.
