Night Train Swimmers enjoy regularly swimming into the beyond, pushing their boundaries, extending their limits and taking swimming to literally where no other swimmers have ventured before.

This is what we do during the shark season,” describes Vito Bialla.

McGuire, director of Shark Stewards, reminds the group, “Sharktober is here. Tell United Airlines to drop shark fin and join 24 other cargo carriers to say no to shark fin. Sign your name here on MoveOn.org’s United Airlines – Stop Carriage of Shark Fins.

Also follow the adventure on the Ocean Voices blog and support shark science and conservation. For additional videos on shark issues, visit here.”
