It is not accessible by foot and most boats can't get in range of the gym due to rocks. When I go to town, the ferry goes close to a lighthouse surrounded by the sea that also hosts a gym. Yet the gym is level 7 for days and filled with 3000+ dragonites of lvl 33-35 trainers (go get level 35 in 8 days without cheating). I know, I have tried on several mobile networks and with friends. The funny part is, it is located in an area where you get no mobile reception at all, let alone wi-fi. Not far away from my house there is this gym. I live in a very remote area, a small village (as in less than 60 people) on one of the islands around HK. What I do mind however is equality of rules. I can live with harder catch rates even though making a CP15 Pidgey more difficult to catch when you're level 22 than when you're level 5 is beyond stupid indeed. For me it is the #1 factor killing the game, by and large. I believe it just gets under the radar for many people.
The amount of GPS spoofing here is so massive and obvious I'm genuinely wondering how come it is not a largely debated feature. I live in Hong Kong where the game was released 10 days ago.
