Downtown is a permanent construction site, and construction means airborne grit.
That dust settles on every parked car and gets ground into the paint the moment someone wipes it with a dry cloth.
Parking is either a sealed structure or a completely exposed upper deck, and the upper decks are brutal from noon onward.
Then there is the glass problem. West-facing apartments and offices take full sun from two o’clock, and blinds are not an answer if you paid for the view.
