However our next trip was better.
We met up with some of J's work colleagues (Kerry, Peter, Anna & Adam), near the College, and headed off to find some caches. All three we were looking for were puzzle ones - you have to solve the puzzle on the website to get the actual co-ordinates of the cache (it does give you wrong-but-close co-ordinates to get you to the vague vicinity). I'd not actually done any of the solving myself (to be honest with the geocaching stuff I'm pretty much just along for the ride, it's a good excuse for a walk and to be sociable). The first one we were looking for was "Ipswich Haven Marina" and we failed with that one :( Peter had been a couple of times before & failed to find it, too. The cache owner got in touch with J and with Kerry after they logged DNFs, so we now know that we do have the right co-ords and that the cache is still there (he checked for us). So another trip another day! (Peter has already gone back and found it, so it's definitely definitely there ;) )
The next two were successful! One near the New Wolsey Theatre ("What a Performance") and one a little way up Bramford Road ("A Cachers Melody"). Both found without much trouble, despite it being dark by the time we got to them.
And after that we headed back into town to get some food, ending up at the Kwan Thai partly by virtue of it still being open at 9:30pm. And partly because it's a nice resturant :)
J and I went back out on Saturday afternoon, and promptly discovered the "Ipswich Haven Marina" cache - not quite sure how we all missed it before, to be honest.
We then (via a coffee in Cafe Nero) headed off to look for "A hard one ..." which J and Anna had solved the puzzle for the day before. We searched for quite a while, but in the end had to admit defeat on that one :( We did check the co-ordinates with the cache owner once we got home & apparently we're right so perhaps it's vanished or perhaps we just need to look harder!
