guys, there are a few places around sydney, including terrey hills, oxford falls, grosvenor (Wahroonga), cross lands and hopeville park (I think thats the name, its down spedding road and is in a bushy area on the park in hornsby heights area). Anyway, I was just wondering whether there are any other places that have good jumps, or lets you build jumps? just wondering how many of you guys live around the hornsby area? thanks.
