Most of the beds that I've found here in Texas are either in heavy cover or some sort of break from the North winds. Other beds I've found are really close to their food sources and are pretty much out in the open or just enough cover to hide them once they lay down.
Another way to tell if they beds are new would be to check for the scat. That'll give u an idea if they are utilizing all the time or if it was just a makeshift bedding area.
Just my 2-cents
