I have a couple of days in a row off next week, so I figured I would take a trip over to Yuma (from Tucson) via the res. Any suggestions on stuff to see on the way or in and around Yuma? I've only been to Yuma once but did not spend a whole lot of time there. I know they have the Imperial Dunes just west of town on I-8, and I'm definitely check those out (didn't get a chance last time). Any other ideas? I'd love to find a good place to check out the river.
