(MSC News)--Two Kansas City men have embarked on what they're calling "a bucket list adventure," riding their bicycles more than 400-miles across Kansas to raise funds for the non-profit Stop Soldier Suicide organization.

The journey of Colonel Robert Thompson and Colonel Dave Johnson (Retired) will bring them to the local area this week, traveling from Washington, Kansas to Hiawatha on Thursday, and then it's on to their final destination: the City of Leavenworth and the Leavenworth Landing Park.

The two men began their 6-day journey Sunday, August 24, departing from near the Kansas/Colorado border on U.S. Highway 36.

The pair, on their fundraising website, say they "believe strongly in Stop Soldier Suicide," a veteran-founded, veteran-led non-profit fighting to reduce military suicide.

Thompson and Johnson have set a $1,000 goal for their ride, with the men saying that donations are tax-deductible, earmarked so that "at-risk veterans and service members will receive free, trauma-informed mental health and wellness care from their trusted team of clinicians."

The pair says they're saving lives and making new friends along the way, as they raise the funds while biking through Kansas communities.
