Lets see... Momentum is billed as a Surf and skate shop. Neither of which can be done anywhere near their store. (Skateboarding is illegal downtown, and the river has no waves for surfing).

Rita's sells italian ice. Not much market for that in the cold months - at least not enough for them to pay someone to stand in the store ant try to sell it.

Look at Carolina Beach's boardwalk area in the winter. Most of that closes too.
