copperbunny:
I also didn't want them trying to get me converted, it's sooo annoying to me.
Now that it sounds like you're pretty well inoculated against religion in general, I don't feel so bad about giving you a few more possible pointers.
I picked a city in Kansas at random, Lawrence, typed in "lawrence ks kingdom hall" into Google and got 5 Kingdom Halls in the area with phone numbers. (None in Lawrence itself, BTW)
If your Dad is/was a JW your best chance at locating him is with the JWs. Posting here is a good idea too, just more of a long shot, IMO.
I know any conversion attempts by the JWs will be annoying to you, but if you really want to locate your Dad I think it's a pretty small price to pay. Be friendly, positive and open with them. Don't come out and say you're interested in studying with the JWs, but a couple of honest positive remarks will go a long way towards making them want to help you.
"I've always admired how committed JWs are to their beliefs."
"All the JWs I've ever met have always seemed to be really nice people."
You get the idea.
Oh yeah, here's the best times to call the Kingdom Hall.
Tuesday or Thursday evenings around 7:15 pm.
Sunday mornings around 9:50 am.
Weekday mornings around 9:10-9:15 am.
Anyone who's been around the area a long time can help you. It doesn't have to be an elder.
Please do me a favor though. Swear to me you're absolutely immune to their recruiting techniques.
