Out of everything I brought over, including computer components, BOOKs, tons of clothes, CDs, etc., I think there was only one thing I brought and haven't used:
Seriously, there is just no where near here (SW London) that I can use them, and from what I heard, it's illegal to use them on the roads. The place I've seen people using skates is the Great Walk near Kensington Palace, but I haven't made the effort to travel there carrying the rollerblades and a bag big enough to stuff my shoes in. Can't be bothered.... I used to just strap them on and go when I lived in the States.
It's crazy. The local parks either aren't big enough, or have terrible paving that isn't conducive to skating. The poor things have gathered dust for more than a year now. Ah well.
