After getting situated, we decided that we would enjoy a gin & tonic cocktail, but discovered that we didn't pack the tonic water! So we rode our bikes to the campground store, and learned that it's only open on the weekends. A guy passing by told us that the next nearest store was across the highway at the El Capitan Canyon resort, so we rode out of the State Beach to the resort. That store didn't have tonic water, but we bought some sparkling mineral water, which yielded some "passable" G&Ts.
