Antarctica: 6 - Snowman, Helicopter (military/scientific surveying), Trip, Pole, Teacher (It's an area that might be taught about), Vacation (Hey - it might seem crazy, but I KNOW people that have gone there for "vacation"). The last two were a little out there, and I wasn't really expecting you to get them - but the words that I figured you might go to instead (Bay, Scientist) were both neutral, so I wasn't worried. Your consideration of Berlin wasn't something I saw coming though, so I had to take a slightly more measured approach after that lead.
Tree: 2 - Nut, Lemon
Piroutte: 3 - Dance, Teacher (something learned), Helicopter (twirling blades)
Flight: 2 - Helicopter, Vacation - I wasn't really concerned with you circling back to Berlin at this point, given Swowl's Gorbachev clue was on the board.
