Only had two of these whilst on a bike, when I was 16 (1961) I had a 125 cc Bantam, and was pottering through Bloxwich High St.when a Jack Russell sized dog shot out from between 2 shops and I went over it with both wheels,I screeched to a stop(well on a Bantam you try and stop) but the dog ran off into the churchyard squealing and I never saw it again.Then about 18 months ago about 4 or 5 of us were on a back lane approaching Buxton,came around a corner and there were half a dozen sheep across the road,we all braked and I think nearly everyone blew their horns,the sheep scattered all to the nearside of the road(virtually a single track road),we got going again and with sods law,just after the bike in front of me passed them, they all decided to shoot across to the other side, except one who decided to go when I reached it, it shot towards me and then did that thing that sheep sometimes do and leapt into the air and passed my face by about 2ft.It was the nearest close shave that I think I have ever had on a bike. 👀
