Thanks, done a wooded path now with the set of textures below. The textures came from CGTextures.com and made seamless using my tiling script. Its really not all that difficult to do.
It seems that the challenge rules have changed and there is no limit on the number of tiles to produce so tell me, what shapes of tile path do you need ?
Also, I am sure you get the idea now - what texture types do you think would be a good idea. I might try cobbles on grass for a city base next.
