You were a Very Wise Man GB, as ever, to be indoors doing useful things.
I was outdoors Notrunning, under what was supposed to be 'cloudy with bright spells'. Yeah right.
Call it 'chucking it down', on a group unprepared clothes-wise because none of us, not one, had proper waterproofs and we were all gullible enough to believe the darn forecast. It brightened up a bit after a wet while, and there was a glass of something not-too-strong and half a dead duck per head to cheer us up later. But half of 300km in the pissy wet, with the wrong gloves, permeable strides and the rest of it, is half too many.
I wouldn't have minded quite so much if it hadn't been for the fact that two weeks back on another longish play-day it was even worse, and I ended up on one of those 'Darkness at Noon' days with perpetuel stair-rods that I swear followed me around, with in that case a dynamo full of water and no 'leccy.
One-off drenchings are OK but, like losing parents according to Oscar Wilde or whoever, one mustn't be careless and lose both.
As for your primary oil, I'm sure you'll be OK with whatever. I only ever sling 20/50 engine oil in every primary I've ever had (except belt drives natch!) including all current ones, and never a slippy clutch in a zillion miles. I was a bit worried looking at your chain as a model of rectitude though - thought I was suffering from double vision there . . . you smugly-doubled-up Plunger People!
