I feel the same way I think (not sure what your thoughts are). Although, I don't think someone ELSE staged the bikes there...I think the girls WERE there and were instructed to leave their bikes. I think they were sent to the lake in some shape or form...not sure how, but I don't believe those girls ventured there on their own.
Aunt Tammy's "gut feeling" of "take me to the lake" never sat right with me, or the statements made about what apparently happened once there. Wylma stated she and her grandson had been to the lake already (albeit just to the parking lot area) and didn't see them. However, Tammy just has this gut feeling to go there, and "jumps out of the car and starts asking random people" (one of which was supposedly running, another story had someone fishing).
If someone was running around the lake what are the odds they would STILL be there and had seen the girls 15 mins prior? I guess I am assuming that the lake's 3/4 circle would be part of a longer run...not a continual run, as the trail doesn't go all the way around the lake. You'd either stop in the parking lot and turn around and go back, or would have ventured onto the streets. I guess I wouldn't have expected someone to still be there (and have seen them 15 mins prior) if they were really just running through the park.
Also, one story had them going west, the next time, east. But yet, she never reports actually following those directions either way - she herself doesn't walk around the lake. She stays in the parking lot until LE show up and guess what's there. The bikes. Huh...what are the odds?
Breault did state there was a "person who runs regularly around the lake" who could pinpoint the time - but I always assumed that person saw the bikes, not the girls. NOTHING ever came about this fisherman who Tammy apparently spoke to, nor TG. All stated they saw the bikes EXCEPT for this person who Tammy spoke with but that's never been confirmed since Breault stated multiple times that "since we have no confirmed sightings at the lake we can't be certain they were there". Just like the comments made about the dogs catching scent - it was "extremely likely they were there" but nothing confirmed.
I do think they were there...I think that is where they were taken from...but I personally don't think it was random. I think those girls were exactly where they were supposed to be, WHEN they were supposed to be.
All just my opinion on the info I have as of now...of course if something new comes to light, I could change that opinion. But right now, that's where I sit.
