JUNE 3-9 ALTERNATE SIDE PARKING RULES

IN EFFECT ALL WEEK Monday, President Obama is in town and doing a whirlwind of stops. He flies into JFK around 4 p.m., choppers to his Wall Street helipad and his motorcade will take FDR Drive North — causing traffic gridlock as he proceeds to 42nd St.. He’ll cross town eastward toward Park Ave., creating traffic freeze streets north and south of 42nd St.

At Park Ave., he’ll proceed north to 59th St., where he’ll dine at a home of a hedgefunder. Around 5:30 p.m., he’ll head toward a fund-raiser at the Waldorf Astoria on Park Ave. using Fifth Ave., creating traffic gridlock on Fifth Ave. At 6:30 p.m., he’ll use Broadway to head south, causing closures east and west as he drives to a fund-raiser thrown by Bill Clinton at The New Amsterdam Theatre on W. 42nd St. Traffic is sure to be closed off between Eighth and Seventh Aves. At 11 p.m., he’s due to head back to his Wall Street helipad. For updates, follow me at www.twitter.com/GridlockSam.

What is a driver to do when there’s only one muni meter within a block, and it's broken or missing? Donald Gilman, Bronx Dear Donald,

There are usually four meters on the block, two on each side. If there's no muni meters on your block, walk to the nearest block where there’s a meter and buy a ticket or risk getting one. Gridlock Sam
