I just entered a contest to blog on an archaeology/anthropology topic for the Guardian UK.
The submission page is rather simple; click on the link and it'll take you to an easy day question form. I know that some of you commenting on this blog have blogs, degrees and professional experience, so just want to throw this out there for the hoodied masses.
I'd post my submission but I'm running through airports this evening. My own idea was concerning the destruction of our archaeological heritage and landscapes. Let me know if you submit something and good luck!
