Slowly learning to play nylon string guitar.
Learning something new -- always have some class our course I'm taking.

ShortCircuit... have you tried Delcamp guitar forum? Might want to join and I'll meet you there... plenty of classical guitar music tabs, sheet music, guitar luthiers, guitar lessons, etc.... great place and I've been a member for a long time...
If I could do my life all over... I'd be a concert pianist and give up everything else, but still have a love of sailing...
