Thanks guys for the responses. It's especially nice for a young guy like me to hear what well-respected veterans have to say.
I've been able to reliably pull freebies off the internet and at nightclubs in Taiwan where I work, as well as at home in the US. I've always been curious about P4P action though, just haven't done it much.
I have some DIA contacts now and if they don't pan out, or turn out to be subpar, I guess there's always LA Cafe. I'll post a report if anything interesting happens.
