For her birthday, Ryan's mom wanted to go zip-lining and invited any of us to join her. Ryan doesn't do heights, so he declined, but I (Christy) decided to join in the fun! Ryan's dad is also afraid of heights but likes the thrill of forcing himself to do something like this anyway, ha ha. As for me, I figure it can't be too terribly dangerous if hundreds (maybe thousands) of people do it every year and we've never heard any local news reports of any accidents or deaths. So off we went! My take on it is that I was expecting it to be a big rush, but it wasn't. It WAS fun though! But no adrenaline rush for me, just fun.
