This Wherigo cartridge plays out the fox-chicken-feed logic puzzle.
The puzzle is this: you are a farmer who has purchased a fox, chicken and feed at the market. You need to transport all three to your farm on the other side of the river, but the bridge is so rickety that it can only support the weight of you and one other item at a time. If left alone, the fox will eat the chicken. Likewise, the chicken will eat the feed.
For this Wherigo, your task is to transport each item from the market on the north side (aka eastside) of the bridge to the farm on the south side (aka westside). Enter a zone to pick up one of the items and walk to the zone on the other side of the river to drop it off. If you choose incorrectly, you will have to start again!
When you have completed the mission, you will be given the location of a physical geocache, which you must visit and sign to log this geocache. You can avoid the road bridge with no footway en route to the final by heading to Tea Pot Island and over the footbridge from there.
This was designed to be a quick, fun Wherigo for people to try while at the Kent Mega. Depending on your logic skills and walking speed, it should take less than 20 minutes to play.

Many thanks to Ranger Fox, who programmed this cartridge, for generously allowing me to adapt and use it. And thanks to Beach_hut for the idea. They say imitation is the highest form of flattery and I loved this one so much, I really wanted to share it with more people!
