MORE DEVELOPERS ARE ADAPTING big-box stores to urban locations. Home Depot in Manhattan? Wow.
There's a two-level Target here in the D.C. area -- at the mall formerly known as Wheaton Plaza, right near where Max Sawicky lives* -- that includes one of those nifty Vermaport cart escalators, which are special cart-only escalators in between the regular escalators. You push the cart into the mechanism and the cart is locked in place and kept horizontal as it moves up or down along the escalator track. The manufacturer's Web site has a nice photo of a Vermaport in action.
* At least according to the D.C. Metro Blog Map.
