Well, a fanmail address that is seperate from his house is one thing. I'm just not into hunting down his home address to send mail like some people I've experienced. There's several variations of celebs and their mail. Some don't have a problem getting it at their home address. Some have a fanmail address but don't like getting tons of mail smothering their regular mail at home. Some don't like mail at all.
It's often a let down to send fanmail to someone who has people read it for them and they never even get to see it. Kind of a waste to write at all. I guess some people get waaaaaaaay to much mail so they have to stop looking at it all. I'm sure Dan has been there and gone through that many times.
It just irks me that some people expect stars to have their email addresses, phone numbers, home address, etc. out there for the entire world to see. Sane and INsane people. People like Anthony Hopkins had some crazy fan knocking on his door trying to get in and kiss him and he asked her nicely several times to leave adn she refused. So apparently he got another house, which is really sad when things like that happen.
I bet when Dan is retired, older and hasn't much to do, he'll probably be a little easier to find in regards to fanmail. Now I'm sure he's busy with raising his kids and working.
Even I'd be tempted to hang around outside his house waiting to catch a glimpse of him if I knew where he lived. I wouldn't though, but I'd be tempted. Some people wouldn't let morals stop them. “You gotta check out my script! It's different than the others you've seen.” Like he hasn't heard that a billion times. He'd try and be nice, but you know he'd get annoyed after so many approaches, and then he'd be sour to those who just wanna walk by and say hey when they see him on the street. I certainly don't wanna risk that.
Bottom line, everyone deserves privacy and Dan doesn't owe anyone anything, so if he wants his contact info kept private, we should respect that and not try to track him down. He's got that fanmail address. If the mail going there is that important, he'll see it.
