Same boat too Chris (and Mike).
I got guitar lessons as a teenager and was in a few bands in my late teens / early 20s. I never stopped playing the guitar entirely but played it rarely once kids came along (and I never learned anything new). Decided to learn properly in October last year and have really enjoyed it. I did what Joe suggests - I went back to basics and did Guitar Fundamentals 1 and 2. Then I moved on to Blues Style 1 and I'm now working through Blues Style 2. I'd recommend this. I learned new things and remembered things I'd long forgotten.
Hope you become the player you want to be!
