Thank you everyone for all the information! Regarding the cache size, my free basic membership does seem to show many more small, XS in my area. I was trying to avoid those just due to being new to this. With that said, three of the ones I have found so far were rather small. There was a pill container, a magnetic flat box , and a small rock hide-a-key type. Each one of those was obviously too small for anything except the log. The rest that I have found were the lock and lock containers which still seem smallish, but I believe were considered medium. Then one very large black twist off container, which was definitely a large.
Also being rather directionally challenged, I am learning quite a bit. The only confusing thing so far is that the maps located in either the Geocaching or the Cachly app, seem to be upside down to me. My location is always at the top and wherever the cache location is, it is below me on the map. I walk forward, the map shows me moving down . This always caused the cache location to be on the opposite side of where I think it should be . Hoping the makes sense. Possibly there is a way to rotate the map so my location is at the bottom, and moving in the same direction as I am? I apologize as I am quite sure that is a silly question.
I am going to take the suggestions and purchase the premium so that I will have access to the many more I can see in my area. I do have two apps in my iPhone.... Geocaching and Cachly. They seem to be linked together, but only the Geocaching app seems to have the option to upgrade to a premium membership.
Would I be correct that I merely press the upgrade button, then confirm the $29.99 purchase through iTunes? I just want to be sure I am actually purchasing the premium correctly?
