Only have experience of the Thames above Oxford so not directly relavant, but what the heck shoot me down....
. This August there were loads of great secluded mooring places that no one was collecting money for (we did pay £4 in Lechlade though)
. Very few boats moving, much quieter than the canals in the Midlands that we are used to
. More that 50% of the locks were self service, initially a disappointment, but they are great locks to work, so really enjoyed them
. The lock keepers that we did meet were fantastic, made you very welcome
. In the summer at lest there was no flow to speak off, nothing like the (Warwickshire) Avon we did at Easter
. Try to use a 14 day license, shorter than that (like we did) is quite expensive per day
All in all loved it, and the Oxford felt very small afterwards. Hope to do downstream for Oxford, but probably not this summer have other plans forming, but that is a different story.......
