You're right. I think they treat the wood on the railroad ties with the stuff.
I've never found the ocean out here stinky. It smells salty, fresh and invigorating to me. Though it can smell fishy or have that mudflat stink in bays or estuaries, especially when the tide is low. It may be a function of where your husband smelled it, or maybe you and he perceive these smells differently. I've never been to Florida, so I can't say if I think the ocean smells different there. The water is warmer, so it may well have a different aroma. We do have a lot of kelp on our beaches out here, and it has a sort of iodine smell. It can get stronger if it's been sitting out for a while during low tide. I grew up in a town by the coast, though, and I never realize how much I miss the smell of the ocean until I visit the coast.
Good to know thanks! I assumed it was more where he was on the island, I couldn't see all those people in California flocking to the beach if it stunk
My best friends mother loves the smell of skunk...go figure! yuck! Oh and bears....they stink....really bad.....like garbage and god knows what else, but black bears are gross smelling.
