Mountain Lion on RT 2

I was driving home from Wellesley R.I. early morning last week- and when we were passing a construction site in the middle of the highway (Colchester/Marlborough area) (rt 2) we spotted a LARGE cat sitting right on top of the heavy machinery looking out toward the highway. There was no mistaking what we saw- the only part missing is that we could not get a glimpse of the tail due to it laying down. However, it was a VERY large cat- it looked like the size of an African Lion you see in photos- and when we looked up the difference between mt lion and bobcat, we are confident it was indeed, a mountain lion.
