SAN MARCOS — Chris Orlando and his son, Ryan, are at a crossroads that few father-and-son duos face together.Call it ‘term limits’ — figuratively and literally. Chris Orlando is a San Marcos City Councilman in the final year of his last four-year term of office. Ryan Orlando, 18, is a standout basketball player at San Marcos High School, playing his final high school basketball season. Both are plotting their next steps. For Chris Orlando, the next step could be a run — for mayor, that is. For Ryan Orlando, it could be a walk — as in “walk-on,” the term for a nonscholarship member of a collegiate basketball team.But both of them are enjoying going through the transition together.“It’s really interesting, as I am considering my next step and watching him do that, the realization that we’re both figuring out what the next chapter is, is kind of cool,” Chris Orlando said. “My son has a strict ‘no pep talk’ policy, so we keep the pep talks to a minimum, but it is neat we are at a new chapter at the same time. It’s been good.”The Orlandos’ respective political and athletic journeys have virtually paralleled each other. The elder was elected in 2006, around the time that the younger first picked up a basketball.
