Every Rivertowns United travel team has B for Boys or G for Girls and birth year as part of the official team name, for example:

B07 Lightning Bolts
[translation: the Lightning Bolts are boys born in 2007 – this does not preclude a couple 2008s playing up]

G11 Wildcats
[translation: the Wildcats are girls born in 2011 –  this does not preclude a couple 2012s playing up]

The prefix is like a zip code -- meaningful administratively, but not needed in conversation or emails or pep talks. When talking to players or emailing families, just say “The Wildcats had a great game yesterday!” On the sidelines, cheer "Go Bolts!" (not "Go B07 Lightning Bolts!").

Teams change divisions each year (U9, U10, U11 and on up) but their birth year stays the same and is "glued" into the team name.
