I always like the walk by a lake or river approach. Simple, romantic, non-threatining. I thinking dinner is part of a good first date but what happens after that is up to the people. I have gone dancing which is my absolute favorite because it gives you a chance to get to know the person. I hope I have given you some good responses.
Skiing is also an idea.
We both think that the first few dates are more enjoyable and relaxed when you are with mutual friends. Even ants can't ruin a good picnic. I met my boyfriend through the personals. About 250 guys responded to that one ad. Since then, we have seen each other as much as possible, he has applied to transfer schools to be with me, and we are always on the computer with each other as much as possible.
