The GPS coordinates on Monday and Tuesday were for locations in Boulder -- near NOAA off Plateau Road and an unmarked road near Owl Creek Drive west of Boulder.
On Wednesday, he tweeted a location near Georgetown.
Thursday, the location was on Highway 72, in Coal Creek Canyon, between Boulder and Golden.
