Neva's dashboard

I'm new to RTA and I've been looking at the online schedules. If I want to get to the CR, do I just catch a southbound bus anywhere and it'll take me there? For example, I live in Arcata. If I want to be at the CR by 1:00, do I just look at the southbound bus schedule and see which bus arrives closest to that time and then see what time the bus leaves from say the HSU library? Maybe that doesn't make sense...It can't be that hard though. Help!
