just counted ours.... 102 lightouses and 5 light ships so far ... surprising how many you see and photograph... well at least I was suprised.
Of course some of these we have visited more than once.
I wish it would be possible to visit all the lighthouses and light ships we have stamps and other philatelic materials for. But to visit 1241 lights would take a lifetime and several fortunes. So we make due with looking at stamps for now
