tube-sock roadblock

(n) Tacky street fair. Temporary pedestrian mall selling inexpensive items such as tube socks, lemonade, scarves, sunglasses such as to impede normal traffic. Crowded street fair that has nothing of worth to purchase.

I would have been here twenty minutes ago but I ran into a damn tube-sock roadblock!

This tube-sock roadblock is a terrible place to spend an afternoon.
