Help Picking a Major (Especially from any SHH Engineers)

[Ragnarocker]

Was wondering if any of you guys could offer some advice toward picking my major. I'm a freshman at Rutgers for engineering and I have to pick my department now. I've been leaning towards Electrical/Computer but I also have some interest in Mechanical and Civil. When I get a job I'd like to maybe design things on a computer in a CAD but I'm not really sure if that falls under ECE or ME. I'd appreciate any general words of advice for picking a major as well... Thanks guys.
