Rode my 77 550K into work all week - clear blue skies every morning; rain and thunderstorms every evening by the time I left.
Couldn't ride today because it was "drop off the grandson day" -- so of course, beautiful skies all day long.
Also got two tires changed on my other 77 550K rehab project - new strips, tubes, etc. - had a buddy help me get a frozen axle nut off of the front wheel - good enough progress for a work night, I'd say. Hoping to get to the forks, brakes and headlamp this weekend at least - and if things go well, maybe even the bearings.
