I'm heading west next month via the southeren route. First up is some tupelo and cypress swamps along the Natchez Trace. Does anyone know of swamps along or near I-20 in Louisiana or east Texas? Next will be dunes. I'm planning stops at Monahans, White Sands and the Great Sand Dunes. Any other ideas for along the way? I was going to camp at White Sands but it's backpack only. Any known cheap motels in Alamogordo? Good food, etc?
