Niagara Falls has some urban, convention center before it was a casino has been in some films. Have you guys seen Optimistic (absinth film)? So much of Mikey Leblanc's urban segment is in Buffalo, a lot of Delaware park, the art museum, and this spot off the 33, also were lifestyles from the falls, and I'm pretty sure that ice they are on is on Lake Erie..
Some friends of mine from Utah did some urban scouting last Christmas when I was home in the area. There was a lack of snow... but we spent all night driving around Buffalo and the southern tier. Most of the stuff we found was around Ellicottville. We found a few that'd be sick, just lacked the snow. I can think of a couple large stairs, a double bridge, and a super sexy stairway in one of the condos at Holimont. With the right lighting, I swear it could make a sexy cover shot. If anyone is interested in hitting anything, I'll be home around Christmas, and would be stoked to meet up with some people and shoot this rail at Holimont. Of course there's always the Ellicottville school, but not that interesting imo, but low bust. It's fun to find rails that are unique and not already "played" like just about everything in SLC.
