over the years I have had many hobbies. but to do some of them now would be too expensive for some one on retirement pay, so I have gone into RC plane flying. wonderful sport. great to be around people who also fly. only thing is finding a place to fly and we are at the mercy of the winds. unless you do the sail plane thing, then wind is your friend. I like metal detecting also and one I really like is astronomy. love to look at the star clusters. there is much more out there than just Jupiter.
