I've been to the Long Beach motorcycle swap meet many times, both as a vendor and as a shopper. It's great! Of course it's mostly Harley-type parts, but there's a fair amount of old Japanese stuff and some old English iron as well. And bicycles. Some very cool old bikes show up for sale there, it's really interesting if you like all kinds of bikes. Where else could you find a CR500 powered cafe racer? Its like being a kid in a candy store.
