Tony, are we offered priority among the attendees at the L2 EVSEs over more local members? I'm lookin' at 86 miles each way, so even with a 6 hour charge, I'm on fumes to get back.
I will put your name on a charger!!! The park is open 24 hours, so you could arrive very early, and be on the charger the whole time. Most locals don't need a charger, but certainly those from Oceanside (38 miles northwest), Fallbrook (55 miles north) and Alpine (31 miles east) certainly might need a charge.
The Mexican border is only 16 miles away, so nobody from the south will need a charge.
86 miles is strong, and remember that you'll be slightly uphill going back. 50-55mph max! I'll bring my tow strap if you come up a mile or two short.
