Just remember, you’re not sick…you’re a collector. A lot of us are and one day we’ll have to thin the herd or sell everything when we get too old to ride. Until then, collect on, ride on! I really see no problem unless they’re expensive to own or you don’t ride 1 or 2 of them anymore, then selling those is reasonable, but if you use them all and keep them all in running condition, I see no issue. Better than gambling or drinking your money away.
