My two cents... if I had the ability (talent/equipment) to modify one of the existing bumper stickers, what I'd do is take the old blue one, remove the italic font, remove the "Free State Project" line, and remove the www from the URL, making it bigger. When the group name is spelled out in the URL, there's no real need to repeat it, and it makes you have to write the text smaller (though I'm sure it's quite legible at it's current size).
However, I prefer humorous bumper stickers to "boring" ones. I tend to get caught by them and go out of my way to read them on other cars I see. If a take on the "Live Free or Pie" liberty diner t-shirt idea was workable as a bumper sticker (or something equally humerous and creative), that'd be my hands down favorite.
That being said, as soon as I can get two nickles to rub together, I'll see about getting SOMETHING for our family's plain, white, boring panel van. Hell, you guys do car wraps? We travel between southern VA and the DC suburbs regularly.

I'm sure I could talk hubby into a FSP car wrap for our van.
