My mistake...I see you did spend time on Lookout Mountain.
We try to get there twice a year (Spring/Fall) going up the back way along the ridge leading up through Covenant College and then onto Lookout. Always sure that we have our passports with us since that route takes us very close to the Alabama border...
Yes we did! Went up to the top, did the ziplining adventure and obstacle courses, and saw Ruby Falls too! I didn't send those pictures to Laz since this thread was focused on our visit.
