I've seen them at East Sector Park at the NE corner. Alligator Lizards are here as well. I've seen photos of ones seen on the Kettle Valley Railway Trail and Othello Tunnel area. Chris, they do look like a dark greenish bike tire tube or something. Tail is shaped similarly to the head as well. Odd creatures!
