As schools go back from winter break, only to find another break due to winter, just how much couch surfing and indoor gaming can one family handle?Instead of sitting around indoors, how about taking a nice healthy walk instead. Most folks don’t really jump at the chance to take a walk in 19-degree weather, but with the holidays making the weight conscience think more about ways to lose those extra pounds, a solution can be found as near as three miles out Highway 8.There you will find Cumberland Caverns where a family can visit and take a very healthy 1.5-hour tour in a constant 56-degree temperature all year round. Since Cumberland Caverns is open seven days a week, and gives tours on the hour from 9 a.m. to 5 p.m., anyone with the will can take a hike that will, if nothing else, work off those lunch calories.“Don’t let cabin fever strike your family and friends again this year,” said Cumberland Caverns marketing director Kelly Roberts.
