Crazy layout

I apologize for the crazy spacing - I'm trying to figure out how to make the posts not overlap each other. I finally got *that* to happen, but sadly now have these awful gaps. Stay tuned as I hone my css skills!

Also - made the switch to Arial. It's less atmospheric, but easier on the eyes, I think. ;) Let me know if you disagree or have any advice on what value to change to the the spacing on track. Muchas Gracias!
