BUG: There was a serious error on upload. I /think/ I have determined that the straight line problem is NOT during tracking but instead happening during upload. This is a huge insight.
The upload stopped for some reason so I cancelled it and afterwards the track was completely messed up but non-existent on the server. A few photos got uploaded.
I tried the upload again and it produced the marker cluster index error which I believe may be due to mentioned items on the map.
The not tracking bug is due to a second BgGeoLocationService instance getting created.
I have to remember these last sections. It started as Wayne described, a driveway single lane mountain road. Oncoming traffic is a real hazard as the locals drive very fast.
It then turned into what Wayne would call and adventure road. Not for beginners. This last section was fast swoppy with dramatic vistas.
