I want to make a road trip through the USA with two friends. Are there any good tools that help us planning this? Like marking spots on a USA-Map, attach pictures and comments, draw lines from one marker to another and so on. It would also be nice if you could see who did what (write a comment, attach a picture...) and maybe even support email notifications.
So far, I only found this one: https://www.myscenicdrives.com/road-trip-planner
EDIT: Yes, I saw this question, but I think my question is more specific (working in a group, augmenting markers with pictures, comments etc.) :) Also I included one of the answers (myscenicdrives.com) in my question to emphasize, that I'd like something more "rich" :) But you are right, I should have included that question at least as reference, so thank you!
