I don't understand why rollerblading popularity went down.  I brought mine to Kauai 2 years ago and they have an excellent bike path right on the ocean that goes for about 8 miles.  I rollerbladed on it 3 times while watching whales.  I did not see another rollerblader at all.  I rollerbladed on the Knowles coastal trail(tricky around Earthquake park), Palmer/Wasilla highway and am looking forward to the new Bogard Rd ext. in Palmer.  Fun, fun, FUN!
