I don't claim to actually know the answer to this question but how expensive could it really be to put up temporary bleachers to seat a couple hundred people for training camp? If you need to recoup the money, set up a hot dog cart.
It's tradition that we get to observe training camp and it's going to really bum me out if we have to rely on the media for our TC report fix, because the content quite frankly is nowhere near as good as what we get from the fan community.
