The Wisconsin Concealed Carry Association is no longer in existence. I started it in 2001, we elected a board in 2007, and then dissolved it in 2008. Bill Schmitz was going to run the group, but I think he just had too much on his plate.
I hope one of the other groups will be able to utilize some of the friendships we made. Jordan Austin was Wisconsin's NRA/ILA lobbyist as of a year or so ago; I'm assuming he's still working Wisconsin.
John Hogan was Senator Zien's chief of staff. He's now the chairman of the Republican senate committee. He was a driving force behind the bill, and he should have some influence over members of the senate (seeing as how he helped get them elected). He'd be a good one to talk to.
Mike Bruhn at Representative Gunderson's office would be another one to talk to get an idea of what might be done.
I'm hoping that Nik Clark and the others at Wisconsin Carry have great success with this.
