Thanks for all the replies and private messages - very helpful. Think I will go for PPL as I am from Ireland and family lives near Weston airstrip in Kildare so useful to have it if I wanted to fly there.
Will go for medical once have done a trial flight (trial flight being more appealing than medical) and I will have a better idea if flying is something I like or just think I would like.
Anybody know the Alouette club in Biggin Hill? Thoughts on them?
