Awww, I'd go on an art walk with you!
I'm planning on going on one next weekend, and it will be solo. Same story. It'll be a fair bit of walking as it's an around neighborhoods type and not downtown, so I'm *really* counting on that little map, lol! (As it's an unfamiliar neighborhood -- but nicer than mine so I'll probably see some nice little gardens along the way too -- bonus!)
I do a LOT of things solo, and can at least recommend them on being able to go exactly where you want exactly when you want. No dragging things out and wasting time with decisions by committee!
