Just stopped in at Summers Past Farms in Flinn Springs on our Sunday drive/errand running and talked to the owner for a bit. I found out after we'd already strolled around the grounds for an hour or so drinking our iced mochas and picking out some plants that he had 110V outlets in the front parking lot and two phases of 110V run to the back/overflow parking. If you have the proper adapter/combiner (and have already modded your trickle charger with the EVSE upgrade), you could conceivably charge at 220VAC.
We chatted about electric cars and hydroponics, etc. for a bit and he told me he was getting a few estimates this coming week to put in a 9kW solar system on his roof. He's going to inquire with the contractors about adding in a solar powered EV charging station in the bid. I've added the 110VAC charging spot to the PlugShare site already and plugged in for a bit as we were leaving to load it up to the Nissan Carwings database (eventually). He's also thinking of adding signage to one of the front spots for EV's!
There's really no charging of ANY sort within miles of this spot and if you've never been there, you can easily spend a few hours strolling around the gift shop, the nursery, the gardens and beautiful grounds. The addition of the coffee and snack/pastry stand was BRILLIANT, IMHO and it makes for a beautiful little oasis in the eastern back country. Now you can extend your trip eastward into the mountains a bit further as well. Alpine and Viejas Casino/Outlets are now within more convenient reach.
I'm thinking that after the solar system goes in we should have one of the local EV Owners club meetings out there for something different! The trip back down the hill is basically free to as far as El Cajon!
The very nice gentleman I spoke to was named Marshall, and here's their info:
