On the topic of meeting people IRL there's an interesting article in the wiki that covers most of the useful suggestions for cases like yours:
Meeting with others - ADISC Answers Wiki
As for me, I haven't been brave enough yet to meet up with someone IRL. The area where I live is not exactly crowded with DLs, and some of these few look really creepy... Then, I chatted with some guys in my age range that souned quite nice and live not too far from me, but in the end we never arranged to meet.
Another thing that keeps me from meeting with others is that I'm very picky and it'd be quite awkward for me to share a so intimate part of me with someone I don't find, to say the least, "interesting", both in a psychological and physical sense. It takes time to convince myself to uncover.... and when I do so, it usually has passed so much time from the first online contact that both of us have lost interest.
But then at the same time I burn with envy everytime I read about other people's successful and playful meetings, I bite my tongue and curse to myself for being such a chicken, etc... etc... etc.... I guess I'm complicate this way.......
As for your meeting, play safe and have a great time!
