Liked the way ya laid things out in yer list, Todd.

We (some more than others...) all to often, get hung-up on one aspect of the problem.

Did you leave out Dams or do they fall under #6?

OOPS! Re-read yer post and caught the "short list" part. Even if it is a short-list I believe that you managed to list most, if not all of the major factors.

Couldn't agree w/ya more

Thanx

Sincerely,
Roger
