Would you be able to take a picture of the pond from I95? And look to see if the canoe is back in place? I doubt it, but it's worth a look-see. Please do not go down into the pond area for your own safety.
The Google photos of the canoe, taken in 2007, show the canoe from every single perspective. But Bing maps do not show the canoe in their satellite photos taken in 2010.
Yet the date of Kelly's disappearance is only 17 days into 2010 (she disappeared on 1-17). The canoe could have been located by the pond right up until that day and then relocated or removed altogether--or hidden. We do not know when the Bing photos were taken in 2010. If the canoe was used, it is possible it is still in the area, just not next to the pond.
I'm babbling. It's been a long day. Sorry.
