Bucky and the team are out looking for dinosaurs and other ancient animals as we speak. Cell phone reception is pretty spotty in the area they are currently prospecting. Footholds are pretty spotty too, it would seem.
Ask any paleontologist how many times they have gotten themselves stuck, clinging for their life on some rock or scraggy near vertical hillside covered in gravel and they will just laugh. Usually a day doesn’t go by when I gaze up to the top of a cliff, sigh, and say to myself… ugh, I have to go up there? It’s all part of the job!
