Hi Spottilludrop, don't worry, I know not everyone is guilty and I certainly don't think you are all feeble-minded, something I tried to convey in my first sentence. One of the best informed spotters I have ever met was a delightful but seriously handicapped young man whose knowledge was amazing and who was a pleasure to listen to. Some of our local spotters are a great gang, friendly, knowledgeable, keen and happy to share their enthusiasm with others. There are some great photographers amongst the ranks of spotters too.
