Can I just say, this is on their way to Leg 3 and I can see in the photos:
Pink Blonde and Male - Photo 1,2,5,6
Boston Strong - Photo 1,5,6
Young Frats/Blue Bandanas - Photo 2,3,5,7
Brunettes - Photo 1,2,3,7
Blondes - Photo 10 (and spotted in Lisbon)
Afghanimals - Photo 8,10 (and spotted in Lisbon)
and in the photo of a team running down the gangway towards gates, the guy has a blue backpack and is African American - so the Lime green African American couple (blue packs)? or secondly San Fran Guys (however they have black packs based on L.A. photo?) - Photo 9
This leaves 4 teams unseen in photos and only 9 teams (possibly 10) could be going to Lisbon:
Rockers
Older Hispanics
San Fran African American Guys or Lime Green African American Couple
Team Bingo
