Prologue:
Ranger Dennis was bored. Most people back home think being a ranger is all about adventures and heroics, and while it's true that rangers see some action, ever since the Legion has been defeated at Hoover Dam, there have been almost no clashes with the Legion. So when Dennis saw a movement in the desert, he got excited. It was clearly not a gecko, since geckos were smaller than what he saw, and certainly not a deathclaw, may god make a special layer of hell for them, and he was sure it wasn't the legion, since they usually travelled in groups. If he had to guess, it was probably a refugee, flocking to the relative safety and prosperity of the NCR. So he radioed his superior, informing him that he's leaving his post and going to search the figure he saw.
