On our way out, the other guy was wearing something BYU-logoed (don't remember if hat or shirt). Some guys on horses were coming towards us, so we got off the trail to let them pass.
As we waited, the last guy said to my friend: "You know they don't allow BYU fans up here, right?" We all just kind of let the comment slide without any response. He then followup up with (head nodding at his buddies), "I just said what we were all thinking."
So, not pointing and laughing, but still a weird interaction.
