43rds street just 1/2 a block away from B'way.

(they used to let just anyone in, and you could eat in their cafeteria.. the food was ok, but the ambiance got a 10! )

Yes, 'blocking the box" can get you a ticket. and the no parking signs in mid town say "Don't EVEN THINK of parking here!" --if you do, you risk a $125 fine, plus a tow fee, and a storage fee, (over $350--plus the cab fare to get to the pound!) --which is why parking garages do business with rates as high as $10 per half hour.

in a head to head (or car to car) race, NYC Parking enforcement would win by a mile over the repo man.. they can tow cars away in a heart beat. (under 2 minutes..)

i have seen them clear a block --with a parade of tow trucks, one after an other--they towed away 10 cars in under 10 minutes!

BACK on TOPIC, while Madison Avenue is still associated with Advertizing, most of the big firms have moved.. some are in the uncool part of SoHo (Satchi and Satchi) others are uptown, (the building (i forget its name..world something) up at 50th street (old madison square garden site--and the building that was the subject of the PBS special 15 year ago calles "SKYSCRAPER" about how big building get built./) but there are very few advertizing firms left on Madison!

in lower midtown (below 34th) Madison is home to ladies (and mens) underwear firms, (Warner Bra's, and Natori and Calvin Kleins)and accessories (gloves/handbags showrooms)
(way down, in the 20's, it's household showrooms, Kitchen towels, and sheets and other household material showrooms-including china, and glasswear)

34th to 42nd some more bra's/and accessories and other mixed businesses.

above 42nd, the low end boutiques start, and the cosmetics. (revlon is 51st street.) above 59th, the expensive boutiques.. (Vera Wang and the like)
