The footpath on Marine Drive is partly blocked by overhanging plants. This caused me to step towards the kerb which has a damaged area (where a under-path drain runs out into the gutter). Because the kerb is missing at this point my left foot dropped into the gutter and threw me off balance right out into the road. I damaged my knee, two palms, my hip but worst of all my ankle is badly sprained. I am only 6 feet tall and walk carefully - the big problem is the overhanging plants which restrict the path and make one look at them rather than holes in the kerb.
