ahh the Maiden of the Mist tour. that was great. Went to Niagara falls on a advanced placement school trip to Canada. costed like $400+ some i think but was totally worth it.
yea makin those Horse shoe falls section would be hard but hey ya never know what tiberium poisoning can do to land scapes

i suggest using 3 of the facings of waterfalls near each other though.
anyways good luck with this map. hope to see a good finished product when the time comes.
