Riding - I'd have to say a good year. Been riding a variety of bikes this year, and feeling more flexible than ever. Before my hernia surgery three years ago, I gravitated toward upright, crank-forward, semi-recumbent, etc. AKA "geezer gliders". First couple years post-surgery were mostly commuting, but this year, I'm feeling much more fit, and amenable to more riding positions. Not a lot of miles, but a lot of great experiences on bikes I wouldn't have considered before.
Trips/vacations - mostly a bust. No bike or camp vacations this year. Flooding in our part of the city late in the summer. Nothing like what y'all had down south, but we weren't able to leave the house unattended for months. Spoiled the Labor Day weekend trip to the cabin/prairie. Our next opportunity would've been Thanksgiving, but truck issues scrubbed that. MAYBE we'll get out there at Christmas...
Collection/builds - Epic. By my meager standards, anyway. Found some smokin' deals, even a few CL freebies. Wife has been having a blast learning how to lube bearings, swap cables, etc. Got really excited the first time she cracked loose a BB adjustable cup lock ring with a Park tool.
2019 kicks off with the Madison bike swap, one of the largest in the country. Down another rabbit hole......
