Departed Casa Grande and drove east on I-10 but only as far as Tucson. We set the Barbarian Invader up in the Pima County Fairgrounds for $20 a night with full hookups. Again, the wi-fi was NFG. The RV area was a big gravel vacant lot which is not too different from the surrounding country which is a big flat area with tough little desert plants. Water, power and sewer worked well. The fairgrounds are about 5 or 10 miles south of Tucson.
