Spelunking is not an easy word to understand for those of us whose mother tongue is not English. As I was explaining the meaning of spelunking to a friend in Sweden, she exclaimed, br Oh, you are a cave man! br To which I responded, br Yes, I am, and I am encouraging people to explore caves as well; that is, their own caves! br Please join me as I reflect upon one year of cave exploration! br In my opinion, it is not so much a question of what we have explored--or possibly achieved--thus far, but rather a challenge as to how can we go deeper!? br Happy New Year!
