Prevent kiosk trail map vandalism?

[MuniOrBust]

It's an exciting time in Monroe County, New York.
There is a large mountain biking community here that's been persuading the county to open its parks to sustainable shared-use trails, where off-road cycling is allowed.

Last year, a trial program began in two county parks. Since then, sustainable trails have been built, unsustainable trails have been decommisioned, and a lot of great work has been done following IMBA guidelines.

About a month ago, the county installed kiosks at some trailheads displaying maps. Unfortunately, vandals have already begun destroying them. I assume they're just some immature kids doing what they do... throwing rocks, cracking the clear plastic.

I don't have an image of the damage, but picture a series of coin sized spider cracks. I'm sure more damage will be done in the coming months, and the maps will now be susceptible to rain water.

Is this a problem at your trails? What can be done to prevent this? Controlling behavior? Building indestructible maps? How?

Here's what a trail map kiosk looks like:

you can get those signs printed directly onto hard plastic that is flame proof and vanidel proof . or you could replace it with a carved board with the same info on

What kills our trailside signs around here is the sun. They look great for the first year or two, but if there was no budgeting to keep them up, they become less and less useful after they lose their color, followed by details.

As your trails become more populated and more common in the area, they won't be such targets for the kinds of brats that do that stuff. They'll move on. But it's annoying nonetheless...
