you're on the right track LuLilac, keep on asking questions - then try to answer them while you're out searching...what else would you call a beacon? if that was a clue, focus on the meaning - perhaps in England, they might call a beacon a ____...where would one of those be where you were?...
sitting a spell helps you clear your mind and focus on your surroundings when caching, allowing your geo-sense to kick in...
allow yourself the freedom to explore and to make mistakes, as your smart phone only has the coordinates to get you within 30 feet of the cache...the adventure is in seeking and the joy is in the find...good luck...
Hee hee. Do you mean a belisha beacon? I don't think there's a traffic light there. There might be. I will check it out.
