My wife and I will be in Vegas for a few nights in May. We are then driving to Moab/Monument Valley area for 1 week where we will be staying in a condo. We would like to pick up some great wines before setting out as I imagine Moab will have limited options. We aren't looking for uber-expensive or luxury wines, but rather delicious wines that offer decent value (we like wines from the Rhone Valley, Walla Walla area, Willamette Valley, Sonoma Coast etc...). We will be staying on the Strip and then driving along I-15. We don't want to go too far out of our way (i.e. don't want to drive in the opposite direction of our Utah destination). Suggestions?
