I do apologise for keeping this post all to myself up until now but I have now got the chance to share it will you all! Last year, I had the very special opportunity of seeing the P4 on a (admittedly very slow) run. In the flesh, it sounds like singing heavenly angels abundant with ice cream, sprinkles and fairy dust. I have no other way to describe it. I also got to sit in it. (I try to brag about that as much as I can.) A massive thanks to the creators, RM Wilson Engineering!
Enjoy the shots and video at the end!!
