Completed two major banners while trying to accomplish this, the Chicago skyline (30 missions) and the UCR Flag at Elmhurst (18 missions).
The Chicago skyline banner snakes through the loop of downtown Chicago. I did it while on my bike, and to say it is challenging is an understatement for one reason, Drift. Being in the loop among the towers makes it a pain in the butt to get to some portals even if you are sitting on the damn portal. I'm not new to drift in the loop, but it had been a while since I really experienced it while playing. I have to say that the start of this banner is rough, with a lot of overlap and backtracking. That said, it gets better as you get to the middle, but you continue to have to deal with the drift. I managed to do it over the course of two nights after work, 12 missions the first night, 18 the next.
The UCR Flag at Elmhurst is based around Elmhurst College and Wilder Park right next door. It turned out to be a nice night tonight to walk around campus. did an excellent job for the most part as pretty much every mission leads to the next and there is only a little backtracking when you get to Wilder Park (at least, that's what I experienced). I did all missions in about an hour and a half. I had to stop and wait for a hack only once (for some reason it didn't register the first hack).
I mistakenly did mission #28 of the Two Towers banner in the middle of doing the Chicago skyline banner....because it was quite close to mission #28 of the Chicago skyline banner and I accidentally chose it and completed it without thinking. I've had to do some manipulation to get the banners to line up properly. When I actually do the Two Towers mission, which I do plan to do, I will need to redo all of the filler missions I did before I did the UCR missions today.....plus an additional one to complete the row.
Before I resumed playing recently, I hadn't completed a single mission before, even though they were introduced well before I stopped playing for the second time. I figured one of the best ways to get all the uniques I needed was to complete missions. A lot of the areas I visited I had been to before, but last time I visited there were a lot less portals....so plenty of uniques for me. Got up to 366 uniques for the month of September....so blew away the basic goal. I don't think I'll get close to getting in the top 20% or whatever gets the second tier badge.
If only this was in the month of October. I'm visiting LA for the first time in early October, and plan to do several missions and get many uniques while I'm there.
edit: and no, no pictures really. I don't take a lot of pictures when I'm out and about playing Ingress.
