Thanks, entropy512 and maingray, I am set up on the WGS84. I know there is a learning curve and expearence only get one better at knowing what to look for but trying to convince my wife that we will get better at this is a different story. We are going out again this afternoon and just hope for some luck. Thanks for everyones help.
Just to let you know, my wife and I went out yesterday afternoon to bike ride and cache. We ended up looking for four caches and found two. The first two we found back to back were micros and were hid in very clever spots. My wife found the first micro and it revived her thrill to cache. We felt we were on a roll but couldn't find the last two. My wife got a little discouraged with the last two DNF's but wants to go out this afternoon.
I appreciate everyone's encouragement that you just will not find them all but the racio will get better.
