I've just set up a hot air balloon tour for EduNation. It starts out at the CALICO/EUROCALL HQ area: http://slurl.com/secondlife/EduNation%20III/36/47/22
This is version 1 of the tour, just set up this morning, so pardon any issues! I'll set up a more complete version soon, and will then be looking for some people to help out with additional language translations to have the tour available in multiple languages.
To take the tour, just right click one of the poseballs in the balloon--you can seat up to 4 in one balloon. If you miss a ride, don't worry! A new balloon will rez soon after one leaves.
Give the tour a try and see what you think!
