When you're ready to put the pedal to the metal in an open cockpit
Formula One-style racecar, there's no better place than Skip Barber
Racing Fantasy Camp. Discover how to race Formula One-style open-wheel
cars courtesy of the Skip Barber Racing Experience. While at the
classic 1.53-mile, seven-turn course, campers learn the basics of
braking, slaloming and double-clutching, with each day getting
progressively faster as skills improve.

Im sure there are plenty more out there. But these are two fantasy
camps one for kids and one for adults.

Children's success in life depends upon the guidance provided by their
elders. If you know children who have an interest in aviation point
them in the right direction ... point them to EAA Air Academy's
Resident Summer Youth Camp. There is no better place to experience
aviation than in Oshkosh Wisconsin - home of EAA. The EAA Air
Academy's Resident Summer Youth Camp is an accredited program geared
for aviation minded boys and girls age 12-18. Professional educators,
Certified Flight Instructors and students from the nation's leading
aviation colleges conduct an array of hands-on aviation and leadership
activities. Sessions include participants that have two things in
common ... the motivation to learn more about aviation and the desire
to be with other kids that share their interests.

Our Fantasy Flight Camp experiences involve an exciting weekend at
"aviation mecca" - EAA's World Headquarters campus in Oshkosh! Each of
our three camps is expert-led and involves a detailed study of a
specialty subject. Every effort is made to make this a true "fantasy"
experience for the aviation enthusiast - including privileged access
to various EAA facilities and specialists. Most important of all, each
camp is capped by an incredible "once in a lifetime" flight
experience!
