LCL.  Got tired of waiting for the other stuff to be finished and had 
the weather stations shipped separately.  But I've got samples due in 
today for another project - if everything checks out I'll have more on 
the way soon.

Freight from LA is the real killer for this shipment, but I don't have 
much choice.
