Farne Islands anyone?

After several years of meaning to I'm determined to make a trip to the Farne Islands this year. The day trip on the boat is quite expensive (£28 + £12 landing fees if you aren't in the National Trust). There would be a (small!) reduction in the boat trip price to £25 / head for a group of 10 or more booked in advance. If anyone would be interested in going along please let me know and I will try to arrange something. I was thinking of mid-late June
