Climacophobia is the fear of climbing. It's related to acrophobia which is the fear of heights. The difference is that in climacophobia it is the act of climbing that causes the severe reactions rather than the height.
A suitable treatment is to be rewarded for a relatively small climb, as in retrieving this cache.
Because of its height. this cache is winter friendly as well as flood friendly if it's not surrounded by water. But if it is that'll help your hydrophobia as well.
Letterboxing directions: Take exit 69 from I35 and proceed to Northfield on Highway 19. At the first stop light turn right onto Highway 3 towards the south. Cross the river and pass the rodeo grounds on the right. Consider the first fast food place south of the rodeo grounds on the right frontage road. The name of the restaurant will remind you of some of the most despicable caches to be found in southeast Minnesota. If you were at their drive-up window at night your headlights would be pointing directly at 300° to a tree 200' away across the bike trail. The tree has rather large boughs suitable for climbing. About 12' out on the fourth bough about 12' off the ground is where you should find the cache.
