Snake or Giant Earthworm

Mom has been training for a triathlon next Saturday and I have been working with her on the running. Several times when mom and I go running we see small snakes. Dad never believes us! Of course when we all go running as a family we never see anything. So a couple days ago we saw this little guy and as soon as we got home from the run mom jumped in the car hoping he was there to take a pictures. This time we could prove we saw one! Dad believes us but is now saying it is not a snake just a giant earthworm! We just tell him we don't know where the mom is and we still don't have to like them!
