We are newbies at this with only 32 finds uner our belt but I do agree that you need to find a few first to experiance what makes a good or bad cache and pick up some tips along the way. I have hidden 2 caches 1 nano in a very busy public area which creates a challenge in its self and the second in a little used beauty spot which is a great spot to take the kids to feed the ducks.
Caches should have a purpose I think wether it be a view, historic, or a challenge to get to.
Anyway we are loving it and my kids cant wait till the weekend to go treasure hunting so thanks to everyone for making this fun.
