Stay aware of who is around you at all times. Look for erratic movements in your peripheral vision and keep a distance from those who might be unaware of how much space they are using. AVOID PASSING Tango is not a race. If the dancer in front of you is advancing more slowly than you would like, alter your dance so that it is more circular and less linear. Learn to dance well and happily without much forward advancement. NEVER ZIGZAG Cutting in and out of line-of-dance is very poor form and disturbing to the dancers you are cutting in front of. If you choose to dance in the center of the room, remain there throughout the song. If you dance in a given lane, finish the dance in that same lane. DO NOT TAILGATE Do not get closer than 3 feet (or the size of a back step), to the couple ahead of you. Give them room to back up. No one is supposed to back up but everyone does even if only to avoid collisions, so stay clear. You'll be surprised how much this can reduce collisions and improve your dance experience!  Always look before stepping back -- HINT: rounded back steps with good contra-body technique are much more milonga friendly. DON'T
