Early '80s (81-82?), MZ250, g/f (now SWMBO) house was 4 miles from my gaff (Googly map link for the curious). For some unknown reason (the fates taking the pi$$, maybe), it seemed that every time I left her place late at night after 'cuddles' it started to rain just about when I left the streetlights ..... ! Now the MZ isn't that heavy a bike, but if you look at the streetview on that link for the last stretch into and through Marykirk, you'll see it's all uphill - ye gods did I get fit!
Eventually I discovered WD40, old Marigolds and bathroom sealant and never had to push the bike again, through rain, hail, sleet or snow - I think that's about the time my waistline started to expand .... ?
