Went to put the bike in the garage last night, and this is what I found. At least it was in my driveway.

Small construction screw. I debated pulling the tire to patch it instead of plugging it, but:
1) I currently do not have the O rings for the spline maintenance;
2) I really do not have the time right now; and
3) The battery on my old SilverWing is toast (beyond resuscitation).
I hated plugging it, as the hole started out the size of a small finishing nail and ended up big enough to shove a gutter spike into it. But I'm up and running until I have a chance to fix it proper.
