[bike] Hilly route to Concord

The group was summoned for a 40ish mile ride, returning via the Minuteman. In an effort to try to get around the problem of there being only a couple of good routes out of Boston, I played the "huh, that street looks interesting" game with the bike map, resulting in it taking 20 miles to get out to Bedford. The other consequence is that some of those roads had little arrows on them, where I've somewhat fastidiously avoided them previously. I appear to have gotten rather competent at climbing hills. Once we got out of interesting bits in Bedford, I basically decided to take the obvious route to Concord and back to fill out the mileage. Route map

Next weekend is the GSW Seacoast Century, which I believe myself to be riding with fredrickegerman. Indications right now are promising -- mostly sunny, high around 77 -- so it's mostly dependent on the wind, and on us not heading full out and being totally wiped by mile 50. After that, maybe it'll be a bit off the bike until spring or so.
