Dangerous trailer "pranks"
Seems that the new fad for the idiots is to unlatch and disconnect chains and even remove receiver pins on trailers when parked at ramps. Have been hearing many stories about this. Friend in Oklahoma had it happen and have heard of it on several Texas lakes.
You get in you vehicle, load and hit road and notice bumping or odd driving. If you are lucky, you get out and find this has happened. It is not a local problem as it seems it is happening in several areas.
Check you trailer hitch, chains and receiver pins before driving
