I like to take in the views, the smells, the wildlife, enjoy the company of my dog and get some nice good quality caches. Anything between 5 and 20 is just fine for me on a days walking. Each to their own. I have no desire to do 100 caches in a day. It might bump my tally up but when I sit back to reflect on those caches found I reckon my memories would be just one big blur.
