I found a game through that site. Exchanged some e-mail, got an address and time for a game, went and knocked on the door. No problems.

As far as your parents feeling weird: They're parents and they're worried you might gamble yourself to hell. Why? Because they're good parents.

Just do what I did (with girlfriend, not parents, but same concern is present) and promise that you'll keep the gamb00l in check, and that you'll be safe.

Basically, that comes down to
a) Only taking money you can afford to lose [and have that be the only money on you, so they won't worry about you being tempted]
b) Leaving if you feel threatened (bad neighborhood, one of the players, etc.)

Still, meeting anyone over the Internet in a non-public place has its risks, so be careful.

As Olmec the temple guide said, "The choices are yours, and yours alone. Good luck."
