Thumbs Up or FU
From Wickenburg to Laughlin this boulder appears to be giving you the thumbs up. However, leaving Laughlin and heading towards Wickenburg, it appears to be giving you the one-finger salute or as others call it, the birdie. I guess it is wishing you luck in Laughlin and sort of laughing at you on the way home calling you a loser. Or it is just a mean boulder, lol.
