Flag Fen is under threat with drainage of the local landscape, plus less water in general (as in, the current drought), so doing as much work as possible to record the site and preserve finds is vital. That costs money though... So Dig Ventures is a cracking idea where you sponsor the work at Flag Fen, and depending on how much you sponsor, you get rewards from accessing information on the dig, to t-shirts, through to actually getting training and taking part in it!
As a way to get backing to help out a site of great importance, this raises money and raises interest at the same time, a sort of fundraising and promotional cross over. They have hit their target for fundraising, but more never hurts and there are 35 days left to donate and reap the rewards of investigating something so unique.

Spread word around, donate on someone's behalf as a fantastic present for them, get school kids interested by sponsoring as a group, achieve an Archaeology merit badge at scouts or guides, add something unique to your student CV - Dig Ventures has a lot to give back for what you put in!
