Sig, DavidG, Bill and I headed down to the National Rental car center and picked up our two 15 person vans and our smaller mini-van. They are now waiting at Bill's house for Eduardo's carpenters to arrive and do the seat removal and build out the storage area with beautiful Salvadoran mahogany.
Amazon delivered the 3rd set of flashing lights although this kind has (too) short a coiled power cable. Hacked a Fry's 1-to-4 12v expander unit to solve that problem. Took each of the laptops out for a spin in the car to see if the GPS units are still working. Things are coming together in my tiny area of responsibility.
