David simply tells it like it is. Always has, probably always will. He's not putting you down, but just giving you an different possibility and in this case, I agree with him. It is a nice size track, but it looks to be in fairly soft soil...almost looks sandy (but you're in IL so I doubt that). While most of the does have already dropped their new fawns, some of the late ones are still carrying them...making them 30 or more pounds heavier than they would be otherwise. If it's a more mature doe, probably carrying twins and therefore even heavier. The weight and soft soil combination can make a track look bigger than it is.
Nobody is trying to spoil your thrill of the find. Simply pointing out other possibilities.
