All Aboard the Hogwarts Express - Potions Traditional Cache

This is a cache designed by a kid for kids (and kids at heart)!!  My oldest daughter is a huge Harry Potter fan and this will be the first in her series of Hogwarts caches based on the different classes at the school of witchcraft & wizardry.

 .

This cache is by a bridge that allows you to be on top of a train going by under you, amazing!! It should be a fairly quick park and grab, it is a one lane bridge, keep your little ones close as you will be very close to the road!! This cache is full of magical potions and she would like to trade in Harry Potter theme if at all possible, magic, potions, let your imagination take over!!  Please post pictures if you can, we'd love to see them! Some stealth may be required at different times, please place back as found, have fun!
