Rawhide is a fake "old west" town set up in North Scottsdale. It's a great place to take out of towners for a little bit of cheesy fun. They have souvenir shops, stagecoach rides, camel and burro rides and shows going on most of the time.
If you want to really do it right, try the Sundown Cookout. A hayride will take you out to the chuckwagon site where you'll sit around the campfire eating "grub" off of tin plates, listening to tales of the Old West, and enjoying live music. Great for a group or a special occasion.
Rawhide is moving to Chandler at the end of 2005, so if you're in the East Valley make sure you check it out then.
