Weekend Away?

Considering heading off to South Snowdonia this weekend. Late notice, I know, but I've not the time to plan an Offa's recce. Shouldn't take me long to bundle my gear into Vera and head off. I'm thinking of maybe following the Rhinogs race route on day one and then something else day two. I've got my maps, what else would I need? All I need is a tall ship - that's Vera - and a star to steer her by... after all, I must get back to the mountains again, to the lonely mountain and the sky...
