Last year there was that Hampton Inn's "Save A Landmark" contest where they ended up giving money to the Admiral Twin Drive-In. I've been keeping an eye on Hampton, haven't seen any new contests.
Here's a link to submit a landmark for the contest. Maybe some folks have a few ideas. Maybe we can get them to have an all-Tulsa contest. [:D]
