Due to unusual circumstances, I was able to not work today, thus allowing me for some time to take pictures. I went to Fore River Sanctuary, and actually found the path this time.. The lighting was troublesome, so I played around with settings a lot.
Today I went out again. This time I explored new territory. I had tried to find "Fore River Sanctuary" before, but seemed to get lost trying to find the trail. Today I accomplished my mission, after u-turning about 5 times. I found the entrance to the place was actually off a side road, not the road it said it'd be off.
