Ride idea...
The factory is very near the Bay Trail - lovely bay views, places to eat at either end, 20-30 miles of lovely cool bike path*!
This would be a totally flat ride. And very unlikely to be hot. (Says BZ, fresh from her near-heat-exhaustion experience of Sunday!)
* The fine print: In the interest of full disclosure, it could also be 20-30 miles of fog and/or relentless headwinds and crosswinds, with surprisingly few tailwind moments. And all the usual irritations found on multi-use paths.
Keep calm and carry on...
