How do I tell my dad that I want to go to a Pride Parade if I'm not out to him yet?

I know it sounds redundant, but I'm just really nervous about asking my dad if he could take me to a Pride Parade. I've come out to him before, and he told me that I was too young to know about my sexuality. That was a year ago. I don't really know how to ask because I don't know what he'll say. Again, I know it sounds redundant, but I just don't know what to do. Advice?
