The site is good. My question is whether or not its worth it to pay the premiums. Maybe I should make a kickstarter page and I can do a full review of the company's features, and then make a potato salad.:)
You can definitely do your geocaching through the site for free, but you need a separate app or device to plug in the coordinates, and you do not have access to many caches. But I still had fun doing it with the good number that were still available after I made an account.
Community appears good. Like on hiking sites, people log in and report that the cache is still active, so you can know when the caches are out of commission.
