I am now aware of 5 Mini-E vehicles out in the wild. Two are still pending permissions to add the owners to my site map. There are likely a lot more that are out there already. I would also like to find out when the first ones arrive on the East Coast. Sounds like soon.
UPDATE: I received email from Joel Sheiner that something like 23 have been delivered on the West Coast with a truckload headed East. Welcome Joel (Mini-E # 005) to the map.
