I didn't have a good answer right there. Of course not. I never do!
But la

Here's the deal.
Yes, you can participant with some groups as a guest paying an extra fee. However, I think having a membership pushes more involvement. the conversation in your head might sound like this, "You know, I better go to this event so I can get my money's worth from it."
But here's more of the deal. And I've written about this before. If you're not out there playing and meeting people, you won't be able to help your networking contacts. And if you stop helping them, probably they are going to limit their help to you.
So my new answer is, "Hell, yes, you need to be a member. It will get you out there instead of you allowing yourself to sit in your office cave."
So there!
