Am I just completely oblivious or is there no map legend somewhere? While most things are self-apparent, such as roads and buildings, I would like to know what the various other things are on my maps, like the purple (and other colors) dashed lines, the roads with choppy bits of color. Are they hiking trails, non-paved roads, or…? Other than that, and the fact that not too many campgrounds seem to be listed, I am absolutely thrilled with this app. Especially after spending literally DAYS trying to download offline maps from another app that just never worked. I put my iPad in airplane mode to test my offline maps and yep, there they were! Makes me much more comfortable using this for my trip from PA to CO next week. Thank you for a great app!
