Yellow Ribbon Project is a thoughtful way to honor those who serve our country! Yellow ribbons are hung on trees along the River Walk as a highlight of the annual Armed Forces River Parade on May 19. Honorees names will instantly appear on the River Walk website through parade day. Proceeds from ribbon sales are used to underwrite the Armed Forces River Parade, which is free and open to the public. Ribbons are purchased online at TheSanAntonioRiverWalk.com for $5 each.
