Four Wheels Inline Skate School

The address above is for Arsenal park, one of the locations where the skate school has lessons.
I took my ex-​girlfriend and her best friend there for Rollerblade lessons. The teacher was very friendly and she knew how to teach. A big plus was that you didn’t have to own your own rollerblades to take the lessons: the instructor can rent them to you if you tell her your size ahead of time. (That way you can take lessons before deciding if you actually want to buy rollerblades.)
