A group of Colorado and Wyoming Model S owners converged on the newly opened Glenwood Springs Superchargers today.
I just posted a report over on the regional sub forum:

Oxnard, California Supercharger--The Oxnard Planning Department gave approval on Thursday September 12th, 2013 to the Tesla Supercharger that will to installed at the Collection at Riverpark, a shopping center in Oxnard, California http://thecollectionrp.com. These chargers will be adjacent to the H & M store as far south as possible within the open air parking, parallel with the 101 Ventura Freeway along the border fence of the parking lot. There will be ten charging bays, all back-in rear-end parking.

We rediscovered what was reported at Supercharger charging rate anomaly because the Silverthorne Supercharger was not operational yet, and we needed a good (>80%) charge to comfortably drive home. See my post at the end of this thread for my analysis of this subject, and what I believe is the cause.
In summary, when on an AC charger (HPWC, 14-50, J1772, etc) the charge rate reported at the car and in the App seems to be the average charge rate of the last few minutes. However, during a Supercharger charging session, the car and the App seem to report the average charging rate of the entire session. This can be very misleading towards the end of a "range" charge on a Supercharger.
For example, when starting with 70 miles State of Charge (SOC), by the time I got to 200 miles SOC, the reported charge rate was 175 mph when reality was 105 mph. At 225 mi SOC, I had 155 mph reported and 85 mph actual, and at 255 mi SOC, I had 132 mph reported and 42 mph actual.
If you want to compute the actual charge rate on a Supercharger, it is Volts*Amps/(308 W-hr/mi).
For practical purposes, if you are on a road trip, this is your last Supercharger, and you need to charge again that day, before you do an overnight charge, then you want to charge to about 250 miles before you leave to optimize your total charging time. A good, simple rule of thumb is to charge on the Supercharger until its current is half of the current at your next AC charging stop. For example if your next charging point is an HPWC that will give you 80A at 240V, then half of 80A is 40A and you should keep charging on the Supercharger until its DC charging current drops below 40A, and if your next charger is a 14-50 RV outlet that gives you 40A, then stay on the Supercharger until its current drops to 20A. This rule is based on the fact that the MS battery ends its charging cycle at about 400 V, and most AC chargers are 240 V or 208 V; 240/400 = 0.6 and 208/400 ~ 0.5. After the half current point, its faster to gain miles at the next charger.
For a 60kWh MS, because 240V/325V ~ 2/3, the rough optimum stopping point for your 65 on a long trip at your last Supercharger is when the Supercharger current is down to approximately 2/3 of the current at your next 240V charger down the road. That, of course, assumes that your next charge spot is not an overnight charge.
Have fun road tripping!
Anyone know which SCs include solar panels? I've done some brief googling and didnt see anything. IIRC, it's only Connecticut (on top of the gas station roof ironically), and the Space X HQ. Any standalone solar installs?
