In the end I couldn't let those 3 rides in the bank go to waste, so I took the afternoon off to get the final piece of the puzzle done. The 3 Rs was enjoyed in gloriously sunny, albeit chilly weather.
Now I just need to get the ride validated and claim my ACME Anvil.
After today's ride, I've completed 3/4 of the ACME winter series. I missed the first one, the 3 Rs. It's available as a permanent ride, but sadly, I'm running out of winter months, as next weekend is already booked.
Still no ACME Anvil for me then, which most likely means it's gonna stay that way forever. Sadface.
