How do I keep my surfboard from flying out of my pickup truck bed?

Question: How do I keep my surfboard from flying out of my pickup truck bed?

Answer: Generally, boards will not fly out of your truck bed as long as you don't have too many boards back there, and the wind isn't inordinately strong. But for those who are very cautious and/or driving a long distance, use some bungee cords stretched criss-crossed across the bed. Rope or any heavy item (e.g. a dufflebag or other soft luggage) will also secure your prized unit.
