The ultralist trackers had set a date for arrival several days ago. Their plan (as I understand it) was to NOT make it immediately known to Rob Young and Company so that they can follow and track without it being known (so that he doesn't specifically prepare for their appearance).
Precisely .... Standby, do not adjust your set!
Additionally, back and recovered from 6-days in Hungary, Joe Fejes is making plans to run with Mr. Young for a couple of days this coming week. Joe should be able to handle Mr. Young's 70+ mile days ;-)
