From the CEC Smart Brief:

Susan Main Hall relates how over the years she used "a few bribes" to convince her son, Benjamin, who has cerebral palsy, to work toward ever-larger goals. To encourage him to walk unassisted, she agreed to take him to Disney World if he hit a home run in baseball and made it around all the bases without his canes.
