acid rain and catchment thread

[Rob Tucker]

I was talking to a Dept. of Ag offical the other day who told me that in past events the volcanic acid rain was corroding fencing and other metals to the point they had a program to share costs with farmers for replacing fencing.

Then I drove to Kona the other day and saw an unusual amount of fresh rust on the galvanized guard rails along the road. Sections further away from the national park were fine.
