As part of the 9th annual Freedom Conference & Festival , a conservative confab taking place in Steamboat Springs next month , the paintings of 43rd President George W. Bush will be on display for attendees at the Steamboat Grand Hotel . 
"This is the first time the -LRB- Bush -RRB- exhibit has been shown in Colorado , giving state residents a unique opportunity to view this popular collection ," wrote Jackson Shedelbower , of the Steamboat Institute , in an email . 
The one-day exhibition on Friday , Aug. 25 , organized by the Steamboat Institute , marks the Colorado debut of Bush 's work from "The Art of Leadership : A President 's Personal Diplomacy" exhibition , which features paintings of world leaders Bush met during his tenure in the White House including Vladimir Putin , Angela Merkel , Hamid Karzai , Ellen Johnson Sirleaf and Tony Blair . 
Although some balked at the idea of Bush as a fine artist when he took up painting in his post-presidential retirement , the 71-year-old has stuck to his guns and humbly worked to improve his art . 
"Portraits of Courage : A Commander in Chief 's Tribute to America 's Warriors ," a book of Bush 's paintings of wounded U.S. military veterans that was published in February , netted surprisingly favorable reviews from critics and topped The Washington Post 's best-selling books list earlier this year . 
"-LRB- Bush -RRB- was really putting himself out there and taking a personal risk with these paintings , not knowing what people would think of them ," said Jennifer Schubert-Akin , CEO of the free-market , nonprofit Steamboat Institute . 
Bush will personalize a copy of the book that is being auctioned on the Steamboat Institute 's fundraiser as part of its $ 75-per-person Red , White & Blue Bash fundraiser on July 20 , Schubert-Akin said , with bidding starting at $ 300 .

[EX Q]: Itâs always the anniversary of something or other. In November  we have the Russian Revolution and the Balfour Declaration  and this week marks the 500th year since  Martin Luther  challenged the Catholic Church with  his  95 theses. Given the loopy Zeitgeist of our times  I should rush into the street and mark the occasion by defacing Protestant churches with the customary red paint of protest. Luther  after all  was more than the creator of Protestantism. He was also a rotten anti-Semite.
But does  Luther  also deserve a splash of red? The evidence is pretty shocking  not to mention definitive. In 1543   he  published âOn the Jews and Their Lies â in which  he  called my ancestors âbase and whoring peopleâ full of the âdevilâs feces . . . they wallow in like swine.â
 He  had all sorts of ideas for what to do with the Jews  including the wholesale liquidation of their synagogues  even homes  and a ban on the teaching of their rabbis âon pain of loss of life and limb.â
To be sure  Lutherâs Jew-hatred was typical for the time  but  Luther himself  was hardly typical.  He  was a powerful  colloquial writer  and  his  words surely had some effect.  He  was the founder of a church  or a movement  that now numbers nearly 1 billion.
But more pertinently   he  provided a religious imprimatur to German anti-Semitism  which culminated in the Holocaust.  Luther  was often cited by the Nazis  but it would be wrong to blame  him  alone for the murder of 6 million souls.
As far as Iâm concerned   Luther  is a flawed figure. I can appreciate â even applaud â  his  reforms  but they mean little to  me . Nevertheless  I spare  him  the red paint because I know  his  Jew-hatred is hugely negligible compared with the Reformation  he  initiated and  not insignificantly  the role  he  played in encouraging literacy.  He  wrote in German  not Latin  and like the Hebrews  he  so despised   he  interposed no one between man and God. One had to read the Bible.
I pick and choose  my symbolic can of red paint always at the ready. But when it comes to those Confederate generals  they unambiguously stand for slavery  racism and the vile nostalgia for the so-called Lost Cause that prompted the erection of so many memorials. I cherish my Bach  feel bully about T.R. and acknowledge the immense importance of Martin Luther. He did more good than bad.

[EX Q]: MIAMI GARDENS  Fla. (AP) —  Alex Hornibrook 's first pass of the night was a wobbler  one that seemed to slip out of  his  hand.
Nearly everything else  he  threw was just about perfect.
 Hornibrook  threw four touchdown passes  three to Danny Davis  and No. 6 Wisconsin capped off the winningest season in school history by topping No. 11 Miami 34-24 in the Orange Bowl on Saturday night.
"We were pretty relaxed "  Hornibrook  said. "We knew we had what it takes to win this game."
The Badgers dominated time of possession  holding the ball for nearly 40 minutes.  Hornibrook  completed 23 of 34 passes for 258 yards  going 20 for 25 in the final three quarters.
Travis Homer and Deejay Dallas had rushing scores for Miami (10-3)  which lost on  its  home field for the first time in 2017. Lawrence Cager had a touchdown catch for the Hurricanes  while quarterback Malik Rosier was 11 for 26 passing for 203 yards — with three interceptions.
"We're all coming back "  Hornibrook  said. "But nothing is going to happen if we don't put in the work."
Wisconsin:  Hornibrook  became just the third Badgers quarterback in the last 15 years to have multiple games with at least four touchdown passes in the same season. Scott Tolzien had a pair of four-TD games in 2009  and Jim Sorgi had games of four and five TDs in consecutive weeks back in 2003. From 2012 through 2016  the Badgers never had a quarterback throw for four scores in a game.
