I gave my brain a break and took the bike out for another trip instead.
This time I drove an hour west to a place called Finns Slough by the ocean. From there I rode to Terra Nova Park and back again on mixed pavement and gravel, stopping at the Historic fishing town of Steveston for fries and a coffee. I added the saddle bag this time because it's quite cold out and I wanted to take a down jacket just in case.
Much better than math
