Freezing rain is just about my biggest headache. We have an ongoing event now and it is a mess. Walking just a 100 yards is very difficult. Does build up your inner thighs, but you need to stop once cramping starts. My female pointer ran through a group of poultry and all of a certain that started cackling like crazy. She fell and slid where she could not get up easily. She may have had last laugh as some chickens flew about a hundred feet and tried to land on the wet ice where they also took a spill. Normally my gravel is the best for walking when weather is bad. Currently it is better to walk on grass and that requires effort as well.
