Gulf of Mexico Tour: Day 4 in Gulfport

Gulfport, Mississippi has two casinos and a beach.

A lone crab. The only creature I saw in two hours on the beach.

Workers trained on this beach to prepare for an oil-spill cleanup if it makes landfall.

The water in the Mississippi Sound -- which is between mainland Mississippi and barrier islands that abut the Gulf of Mexico -- looks strikingly yellow. A local told me muddy water is normal.

A thunderstorm looms ahead.
