On Tuesday’s St. Louis on the Air, host Don Marsh led a conversation on the topic of bike safety in light of the recent arrival of the bright yellow and green bikes around town and the presence of more cyclists in general on local streets as temperatures climb. Joining the conversation were Taylor March, advocacy and education manager for Trailnet; St. Louis Public Radio digital reporter Kae Petrin; Sam Sadle, director of strategic development for LimeBike; and Lori Winkler, an injury-prevention nurse and coordinator of Safe Kids St. Louis at Cardinal Glennon Children’s Hospital.
