Ok I am sure my answers are in this forum somewhere but I figure no reason not to just ask and see if anything new is said.

I have a 10 mile eastward downhill ride to work, paved but some parts have heavy traffic. I then have to go north 8 miles to get to class in an hour. (biggest fear is security at school!!) Then I have to go southwest about 9 miles home, uphill dark. Advice?
