I was in from 1969-1974. Dropped it for the college life because no money/no time. I thought about it for a couple of years and I then picked it back up in 1981 to 1987 and then dropped it again when #2 son was born and I lost my work room and also my launching time. When the oldest got into Scouts I saw the Space Ex MB and picked up the hobby again in 1995 and have not stopped since then.
