the big time eater for VS would be (a) the drive to Cocopaara Park (b) gathering the materiel to light a fire, out of damp wood , even though he had a can of gasoline, it still has to take hold, and a fire to burn a body, well... that's a damn big fire.. that's logs, and dry logs at that, and a hell of a lot of tinder and kindling to get started with, probably have to dig a pit to get a wind break...a short but heavy shower of rain in the area on Saturday would still have effects in the Park on Sunday, then the (c) drive back from the Park.. the drive up and back would be a careful one for sure , and VS was on an unknown time schedule. He had no way of knowing when an alarm would be raised.. he might have minutes, he might have days, he doesn't know. No wonder he is hurling stuff in canals in broad daylight.
