Hike No. 4: 52 Hike Challenge: Moses H. Cone Memorial Park and Grandfather Mountain. We hiked briefly at Moses H. Cone Memorial Park yesterday but the rain, thunder and lightning thwarted our goal so we had to abort the hike after just 0.5 mile. However, earlier in the day, we visited Grandfather Mountain, crossed the famous Mile High Swinging Bridge and scaled the immense rock formations on the other side. We also checked out the nature habitats for a distance of approximately 0.5 mile. Total Distance: 1.0 mile.
