When i was a lad. I arrived in Manly Manly as a 12 year old. Aussies had surf boards, skateboards, & BMX bikes. My old Country had none of it. except I'd heard of skateboards. Ceratilnly never heard of BMX until I came to AUS.
I arrived here in 1978 I recon by late 1979 or early 1980 I as right into BMXing. I was a BMX head. Big time.

There used to be a BMX track in Seaforth. Near wehere now there is the pump track behind the comunity center right next to the tennis courts.
In fact...I can see the pump track from my balcony right now.Its called The Grove.
