I found the first 2 today. Was only going to do no 1, as I wanted to drop off a Geocoin that I have had in my possession for too long, and thought that a premium member first cache of a massive series would let the coin get picked up quickly and by serious cacher. The coin wouldn't fit in the first cache, so moved on to the second, which it did.
From my limited experience of the first two, they look to be just as as easy hides as the nearby GCW series, but better*.. in that they were not just film pots.
I think it will be the summer before I could seriously attempt doing a full loop, or possibly doing a
@tarmacjohn and doing the lot in one go.
*edit... "but better", not "but no better". Bit of mistake typo there.
