Many professional racecar drivers started out racing go-karts, just as many jockeys worked their way up from ponies and many astronauts practiced on merry-go-round rocket ships. Play toward a greater future with today's Groupon: for $11, you get an unlimited ride pass (up to a $21.95 value) at Cartland of Cape Cod in Wareham. This deal expires August 31.

A destination for family fun near the Cape Cod Canal since 1970, Cartland grants kids the keys to spurn bicycles for a fleet of exciting track and water rides. Break free from the chains of ride restrictiveness with the unlimited ride pass, which bestows all-day use of five different attractions. Kids can practice evasive maneuvers in rush-hour traffic in the Indy-style go-karts or hit the slick track, which is like sprinting on a hardwood floor in motorized socks. Stinger karts, designed for drivers 48 inches or taller, bumper boats with built-in squirt guns, and adventure mini golf round out the recreation Rolodex.

The unlimited pass also grants the holder one-dollar rides on the splash attack, where participants shoot water balloons out of a slingshot at each other or hold off an advancing horde of wicked witches. Like the NBA, Cartland requires that its youthful participants are a certain height for various merriment opportunities, so Groupon buyers should consult the website's description of each ride's tallness demands.

Though Cartland of Cape Cod sometimes features a discounted price online, this Groupon still offers the best deal available.
