Tig was supposed to be 66lbs to ride the zipline, but they let him go even though he was about 60lbs. Mainly he needed more weight to get across the last line that goes across the river - sometimes if you're too light, you get stuck in the middle and a guide has to get out in the river with a big stick to drag you to the end! He was elated to make the last zipline with a good speed!
