I don't know if DC & NYC are interested, but Toronto is hosting a city-partnered Bike Polo Tourney in early June this year. Attractions include a beautiful venue, competition, spectators, a road crit the same day around (literally) the bike polo fields (2 fields). Housing can be arranged though I'll need a few days to secure that information & contacts, 6 days actually.
You'll face Toronto, Montreal & Ottawa (NA Champs those Ottawa people) for certain, and we're also inviting Philly, Portland, Chicago + NYC & DC of course, others too if we find them. Ottawa is smashing power good apparently, they are the ones to beat!
any interest...hmmm. hmmmm? yer notz the cowards are yous?
