Here are just some of the tasks where assistance will be needed :
Help move boats from TDBA to race site and back - very early meet time, ends well after racing is done
Race site set up - also early start; set up event tents, heads/tails on boats etc
Race site tear down - opposite of set up; also trash pickup
Racing - as a steers, drummer, or paddler for community teams; there will be a sign up for steers and drummers; paddlers may just be able to hang around in marshalling
A TDBA contact will work with you.
