Sadly, over the 2017 holidays our little family of robots lost a much-loved (by some) and much-reviled (by others) member–the little blue Dodge truck I ordered off Amazon way back in 1999 lost its ability to turn. So after much dithering at various hobby sites and much scouring of Amazon, we purchased a suitable replacement.
We were unwilling to just toss away our little blue truck though, so it was given a thorough cleaning and now resides safely on a shelf in the guest room. So if you come stay at Purgatory, you can try to spot the holes in the wheels that Thy made long, long ago.
