Thank you Todd.

So, I need to start watching WG's as well as everything else or will watching the normal BP and RH along with Vapor Press give me a good idea of how much water is in the air?

Does anyone make/offer a stand alone devise for measuring water grains?

For the record, I really need to get a handle on this mainly for the small cars. They run on an index and if they are gonna pick up do to the conditions I can't just dial them faster. I have to either add weight or tell my drivers that conditions are right for them to go faster so they know they may need to do something at the stripe.
