a trek always starts with everyon sticking to the group...and then like a cycling race, every one finds their pace. its like the bell curve. nothing different here.

and every trek that i have gone too...and have heard this from others as well, there is always this one dog, u meet right at the start of the climb, and he would follow you right till the top. sometimes even leads the way, but never will come to u to be petted till you reach the top. then will come for his rewards. its happened to me thrice now....
