Because someone just reminded me:

Due to the nature of a forum, you can spend a lot of time interacting with someone without actually meeting them face to face. Of course, being a local community like we are, there have been opportunities to meet and greet which has made this whole experiment a lot of fun for many of us. Even though we drove him nuts sometimes, Rumbler loved this place.

One thing I'd like for some of you guys to know, it didn't matter if you met him face to face or your only interaction was here on the forum. If he treated you like a friend here, you were a friend. You do not need to feel like an outsider looking in. You are welcome to grieve with the rest of us as friends of Mike.
