Yes. It's about the only raifanning I get these days outside of what passes through town at home.
As far as I know it's gotta still be there. As of about four months ago there were no signs of replacement. It's just south of town (between US36 and town) and has a convenient access road off of the main drag (MO 129). (Oops... now that I look at the maps you linked to.)
We will be up that way in about a month, en route to/from recurring job stuff in Omaha and Lincoln. We always stop in Bucklin, as it is the midpoint of our road trip. There's a great tree to nap under in a church backlot where the ex-ATSF crosses over the ex-CB&Q. Traffic is very heavy on this line - no nap, no matter how short, goes uninterrupted.
