Journal VS Blog

I am not sure what I want I am going to do about the whole senior blog thing. I feel that if I begin a blog that it will be hard for me to write in it everyday because I do not have internet access. My dad had a wireless internet card but he has to pay for it to be turned on. If I write in a regular journal it might be a easier way. The thing is that I really wanted to do a blog because it goes along very well with my senior project.
