4. Boiler Bay, Oregon Coast

Cars can turn on their radios and learn more about migrating gray whales and how to spot them.

Oregon Sea Grant has teamed up with the Oregon Parks and Recreation Department to test low-power radio as a means of getting environmental information to state park visitors.

Using a compact transmitter and antenna, the low-power system broadcasts a series of messages within a very limited range -- in this case, about the size of the parking lot at Boiler Bay, just north of Depoe Bay on the Oregon coast.

During Whale Watch Week, March 21-28, the Boiler Bay transmitter will air a series of messages describing the biology, natural history and migration patterns of the gray whale. The tapes also include information about how to spot the whales as they swim past on their annual migration northward to their summer feeding grounds off Alaska, and about Whale Watch Week activities up and down the coast.

Radios should be tuned to 1610 AM to pick up the broadcasts
