@neauoire if it's C-Maps, I happenstanced upon a guy selling the carts for the entire Inside Passage from Olympia WA up to Elfin Cove AK. if you two need or want them, holler and I'll make sure they get to you some how, some way :) they're old, but I have to assume at least vaguely still kinda useful in broad terms

@klardotsh ah yes! it's a C-MAP cart, but it's orange and it's quite a bit smaller than the pictures on craiglist.
