1) The Knicks and the Boston Celtics will play game three of their best-of-seven series Friday night. The biggest difference between Friday night's game and the two previous engagements? This one's in Boston. Analysts figure if Boston is going to make a push and play for pride, Game 3 is the time to do it. But the Knicks don't want the series to drag on longer than it has to and are expected to play hard for a win, which effectively would seal the team's first playoff series win in more than a decade.

2) The state hasn't given up on bus and rail options for the new Tappan Zee Bridge, and on Friday morning New York's Mass Transit Task Force will meet at the Crowne Plaza in Suffern to talk about solutions. The task force is expected to focus on ways to finance transit options on the new span.

3) Friday is Arbor Day. Normally, the quasi-holiday is a bit of a snoozer, but this is the first one since superstorm Sandy destroyed thousands of trees in the Hudson Valley. In an effort to get people to begin replacing those lost trees, Westchester County Executive Rob Astorino will plant a seedling during a 1 p.m. event at Saxon Woods Park in White Plains.

4) The NFL Draft continues Friday after beginning Thursday night with the selection of the top picks at Radio City Music Hall. A few familiar faces from the Hudson Valley have draft hopes.

5) Horse racing returns to the area Friday with opening day at Belmont Park. Racing fans can catch a direct train to Belmont from Penn Station, which also entitles them to an admission discount.
