long time!
spend a lot of time in the south dealing with getting a car sorted for my gf, a bunch of visitors from germany with much champange and a lot of teaching this week, so I haven't been riding as much as I'd like. on the upside, I'll be in germany for a long period such that I can get some time on the old MTB and drink some Glühwein at the Christmas Markets!
flat tire (tube) was £2.99 to replace (as of today that is $4.7, so I'll round to $5 and add it to the total)!
however, i did hit the pothole so hard that I think I broke the sidewall carcass on my rear gatorskin ... it now has a slight bulge

... but I'll run it until it fails.
stats:
3132km/1946mi
£547/$870 total
£0.17/km
€0.21/km
$0.44/mi
net money saved (bus fare saved minus running costs): £69 (1 month bus pass) + 8 days (£37.6) + 11 days (£51.7) + 10 days (£47) + 5 days (£23.5) = £229.8/$360.80
net maintenance since breaking even with the bike. £2.99/$4.7
still on top (but the chain is in dire need of lubrication)
