Hi man, my name is Peter and I live in Marpole as well... in fact I often play with another guy who lives around here
not sure about our exact level, but we're pretty advanced so 4.5 sounds about right, if we can find one more player we could even play doubles sometimes
anyways, keep in touch, you can post on this forum or send me an email at peterfaure@hotmail.com, put tennis in the subject
