what all is on it or how is it in comparison to Ocmd or Rehoboth Boardwalk?
Fenwick's boardwalk has a small strip of eateries on the bay side. Rehoboth's boardwalk, facing the ocean, is better IMO.
Take the typical junk food you'll find in a block-long stretch of the OC or Rehoboth boardwalks (french fries, ice cream, Fisher's popcorn, etc.), then situate those stands along a busy highway where you can inhale car exhaust instead of sea air. Then pave the 100 or so feet of storefront with wooden planks instead of concrete so you can justify putting a huge "Boardwalk" sign on the highway, 'cause it's more likely to bring in gullible parents than if it read "Junk Food Strip Mall."
In all fairness, Fenwick has neither a "real" boardwalk or commercial activity along the oceanfront--so all the businesses are situated along the highway. The Boardwalk gets an A for effort in trying to simulate the Boardwalk experience in miniature given the limitations of Fenwick commerce. But if your kids know about the "real" Boardwalks in OC and Rehoboth, they'll be begging you to get to them quickly.
I totally agree with Tubman. They could put up 100 signs but, that's not a boardwalk.
