thanks Lakitu and jen78. have recently taken up running which I absolutely love, but the impact on my joints is just killing me and I thought roller skating might be the next best thing. Did you roller skate outside on the pavement ?
I loved rollerskating when I was a young man,& when I went on holiday to New York City I was fascinated to see how many folks of all ages rollerskate(& blade) in central park, I wish someone would start it up in the UK(at 83 I think I'm too old).
