I log my finds in the order that they happen, and let the milestones fall where they may. Much of the time they occur in the middle of an out-of-town run, so there is just no way to plan a special one to mark. One that fell very nicely was the virtual at Geronimo's burial plot, in Lawton, OK. But that was just luck. I've had them on a power run, an LPC, etc. I won't drive miles out of the way or make special plans for milestones. I make an itinerary before I leave the house and stick to it, as much as possible. Just one DNF would throw off the entire scheme on one of those runs, if I were trying to target a cache for a milestone. It would be sweet to get a FTF when a milestone # comes around though! But I won't wait around, anticipating it.
