Getting on my bike

I'm a bit lazy on cold winter mornings but if the cost of petrol keeps going up, I'm going to seriously have to think about getting the bike out and riding to uni once semester starts again. I know I should ride more often but there's the whole thing about how much time it takes and carting all the things I need with me. I guess I could just eat less - hmm, I don't know if that's a real option. Rising costs of petrol must be really hurting some people though, even more than me.
