Rosie's is a big tourney for the area (WNY). I know that in years past, as others have explained, it had big exposure. I'm not sure what has changed. I know this year at 14U we considered staying back to play instead of traveling because the teams list was looking good.
If you want to do anything outside of softball I can direct you to the best food places
The falls from the US side may not get a good view of the horseshoe itself, but you are feet from the rushing water on the American side. I mean, 2 - 4 feet at times. Hold your kids tight, the railing is just for looks. Growing up out here my mother used to say "the water called you" to us as young kids. I never understood what it mean when I was young. Now that I am old, I know what she means. It really is breathtaking.
Again, feel from to message me with any questions or suggestions.
