Talk:2987: Tectonic Surfing
Where is the speed Beret Guy's moving at coming from? It looks to me like he moved about half his own height in 20 years so assuming he's 6 ft: 36in/20year gives 4.57 cm/year 7 cm/year for his speed seems high and 11 seems ridiculous. 172.71.159.45 (talk) (please sign your comments with ~~~~)
