Lot of criticisms here, so I'm a little reluctant to pile on. After the first crash I would have hit RTH to inspect for damage, no guarantee the bird makes it home if something is wrong, but better than continuing as if nothing may have happened, especially with the possibility of losing control and hitting someone.
Also a little disturbing, because it soils the reputation of drones in general, is that your flight seems to be a "spy mission" on the campers across the river. Stopping at each site like you did could be upsetting to people having a reasonable expectation of privacy.
