Alrewas to Branston

The mooring at Alrewas was rather nice as was the time we spent at the National Memorial Arboretum at Alrewas. We walked there, which was a little scary along the A38. Having arrived somewhat shattered, we found out that we could have caught a bus grrrr. So after an emotional walk around the Arboretum, we caught a bus back to the village for £1 each. If you have never visited the National Memorial Arboretum at Alrewas, you should go, it is an amazing place.
We are now moored near the "Bridge Inn" at Branston, where the pickle comes from, 5.2miles 4 locks. We have had some engine overheating problems again today, so whilst we pulled into Barton Marina to buy a replacement pole, I took the thermosta...t out. There is an air lock somewhere and I just can't seem to shift it.
