Now this sounds like fun! Mum and I are fairly adventurous - she's gone up in hot air balloons, we've both gone canoing together, and we love hiking.
We came across this site today that specializes in unique gift giving. They say they believe gifts should be given, received and above all else experienced. Sounds like a great philosophy to me!
The company has a wide variety of interesting and exciting activities, ranging from Helicopter Tours, culinary classes, dinner cruises, America's Cup sailing tours, and even car racing experiences. We will definitely keep this site in mind for either a unique gift, or a fun time for us the next time we're on vacation! Very cool.
