Read this, watch the video underneath. Wow.
Eighty-five times [Dick Hoyt]'s pushed his disabled son, Rick, 26.2 miles in marathons. Eight times he's not only pushed him 26.2 miles in a wheelchair but also towed him 2.4 miles in a dinghy while swimming and pedaled him 112 miles in a seat on the handlebars--all in the same day.
Dick's also pulled him cross-country skiing, taken him on his back mountain climbing and once hauled him across the U.S. on a bike. Makes taking your son bowling look a little lame, right?
