Dark is just the absence of light so I don't think it has a speed, unless it's a black hole but even then I think it just pulls stuff into it so the stuff is what has the speed not the hole right? This probably requires google but too lazy.
I was thinking of going to the barn tomorrow.My trainer was going to teach me how to jump since I am just learing. most people have tomorrow off I'm scare that everyone is going to be at the barn.All of the other girls you're right there are much more experience than me and it's giving me anxiety!!!

What kind of underwear do you where when riding? I always get underwear lines:((
