My first roller coaster ride

It was a day of fun and a perfect time with my family. Since of a surgery I had when I was young so I couldn`t ride some of them and others I wasn`t fond of riding since of my fear of heights.  I rode on two roller coasters that took myself and family up to I say about twenty to thrity feet in the air, which then lead to a drop. Yes it was fun but at the same time horrifying. If you have any times on roller coasters that frighten you some how please write it in the comment box.
