Hello Little Mermaid,
Welcome to YD from another new-comer (recently joined)
I too have been spoilt thus far, I did my basic OW in the caribbean and my advanced OW in New South Wales so looking to 'toughen-up' by diving in the UK this year. Having said all that I am still very, very new to the game only having around 20 dives to speak of in the logbook!
Have you any experience of local clubs in Lincs? (I am living in Lincoln at the moment)
