Escondido start: We could start at a supermarket on E. Valley Parkway. This would be just west of where we would normally turn onto E.V.P from Bear Valley Parkway. This will be a minor/easy change to the route. I estimate that this would put us one hour behind.
I think the Palomar store opens at 10 on weekends, maybe 11. We don't need the store unless someone needs food. There is the well water 1/2 mile before the store (turned off on 11/15 but I'll check it before the ride) and a hose bibb behind the store. We'll be mostly descending until the Lake Henshaw store.
I suggest we stick to the original Harrah's start and decide on Wohlford Rd. later. At least until I drive out Valley Center Rd.
