Well think on this Tiompan - when you're long gone and dead ;) how would you like to appear in the literature as the 'amateur archaeologist' who found several important rock art stones, etc.. It would be interesting to link all the things you've found eventually.
Just been reading about Basil Brown, (amateur arch.) he who excavated Sutton Hoo but it was taken away from him and given to 'proper' archaeologists to finish the job, they're trying to find funds for a memorial atm, because they don't know where he's buried.
Its funny there has quite a few news reports on the 'new find' all more or less saying the same thing, but stressing the 'amateur archaeology' bit but with the backup of the professionals...
