Day 3 plan

Day 3 looks like a nice walk through some preserved wilderness and the beach for the rest of the way to the campground at South Carlsbad State Beach.

That illustrates a major problem of this trip.  The fee for this park is $35 a night.  Far less expensive than a hotel, and more appropriate for my purposes, goal, and message, but how do I pay the State of California in Bitcoin?  Convince someone to pay in cash in exchange for Bitcoin?

Also, the check-in time for this campground is 2PM, and the website and brochure specify that there are no exceptions, so I'll need to get the 15.6 miles in before 2 if I am going to stay there.

Problems, problems, problems.
