I've never liked them and have only rode a couple and then only because someone I loved encouraged me.
With names like Thunder Road, Mindbender, Avalanche Run and Afterburn, roller coasters frighten me. In fact almost all rides at fairs and amusement parks send my stomach reeling and for that reason I've made a lifetime habit of avoiding most of them; roller coasters particularly. Sudden starts and deep drops, turning upside down and fast speeds make me uneasy.
