Thats interesting... You should pay someone for a hot air balloon ride somewhere around there and see if you an get a really high up sighting of it. Or you could get a string with alot of helium balloons connected to a high sky scraper and connect a camera to it... make sure the string is long. Maybe an rc helocopter or something to get a really high veiw of it.

I would love some pictures or videos, if at all possible, seeing as there is so many sightings of it.
