31 years old, am I too old to go to engineering school?

So I've been working in IT for the last 15 years of my life, (6 years freelance, 9 years professionally) and about 2 years ago I finally decided that I'm getting burned out and need a career change. I enrolled at the local community college and starting taking classes at night and online. I now have enough credits to transfer to a decent 4 year state college in my town and I'm thinking I want to go into engineering. I've always enjoyed designing and building stuff ever since I was little, so I think it would be a good fit for me. I'm just concerned that I may be a little too old. I met with an advisor in the engineering department at the state college. While she was encouraging, I looked around the department and I didn't see one student my age. I realize that I'm a non-traditional student and that I'll be a minority because I'm older than most students. I just want to make sure I'm making a good decision here. Will my age affect my employment opportunities once I graduate?

Edit: Wow, thanks for all the replies. From what I've been reading it sounds like my fears are completely unfounded. I guess I just needed some reassurance from some people that have actually done this before. None of my friends or family are engineers, so this is all new territory for me. I've got another semester of Calculus and Physics at the community college and then I'm diving into the engineering program.
