Probably the nicest church in Tbilisi, stands out from other buildings and there are still masses held daily. You can enter inside only if you're dressed accordingly.
Fun little drive through the desert on a day when you are in no hurry. The store at Cool Springs is fun to look around as well as the landscaping throughout the drive. A lot of switchbacks near Oatman. A few nice overlooks, a working gold mine, and donkeys along the roadside add to the fun of this drive. Just don't be in a big hurry. Life is simple out here.
