MotoGP has a love-hate relationship with the Indianapolis Motor Speedway: most of the paddock love the place, the rest hate it. The way those feelings are divided is what is really interesting, though: the admirers of the track include most of the media, the teams and many, many fans. Those that hate the track are a small but well-defined group: anyone either wielding a camera or a racing a motorcycle have very few kind words for IMS.
So why the schism? It really depends on what you are doing at the track: the circuit has some of the best facilities of any circuit the MotoGP circus goes to all year, making the life of the media, the teams and the fans exceptionally easy. The photographers, on the other hand, hate the track because of the fences. As a circuit that mainly hosts car races, there are high chain-link fences all around the circuit, to prevent debris from wrecked four-wheelers from flying into the spectators.
At a few selected spots on the circuit, there are openings in the fences for photographers to poke their lenses through, giving them an unobstructed view of the circuit. There are lots of photographers and relatively few camera holes, leaving gaggles of photographers gathered around the available shooting spots like narwhals around a breathing hole in the arctic icesheet.
