Feel for you. I lost a paddle once.
Did you have people with you? I think that most Waterton paddlers might be scratching their heads trying to figure out how you could lose a boat in Waterton, because everything ends up in the Res with a huge flatwater pool ahead of it. Hope you get your boat before one of the fishermen does. I really do. If you contact the Res. they can help, if it's not there check Craigslist, area Pawn Shops, and the Mile High Flea Market.
I love to dance, but who needs the music- It throws me off.
