I have a minimal mention: "Leisure: travelling by plane and campervan, playing music". It is rarely entered upon during interviews, the one time my leisure activities were discussed it was when the interviewer had an interest common with mine (at that time), editing OpenStreetMap.
P.S. I heartily second OC619's PS. At least over here, spelling is rather important to first line recruiters, it is an easy sieve for them.
