Huntington Beach has changed alot. There are tons of shops, restaurants, movie theaters etc. We saw Finding Nemo for the first time there, and walked out of the theater to hear seagulls, and I swear they were saying Mine, Mine, Mine!!!! LOL
There was a cool kite shop on the pier too as of 2003. My ds and his cousin played on the beach for hours, digging up shells, little crabs and just playing in the water. I was fun for me to watch the surfers.
I remember back in the early 80's there was hardly anything there, just a few surf shops.
Have fun!
