ah yasss.. so true.. good point.

also on this subject (sorta) rich does a really good job on his article in
this issue of AC about diving off the lava flow.. i'm starting to think the
guy is gonna be a terrific writer.. he describes the dive perfectly.. seems
that he left out the super cold upwelling water tho.. don't remember.. anyway
you all should check it out.. good photo as well.. don't know how he got that
tho, we never had more than six inches of viz until we got to 220.. 

aloha,

dennis
