Coastal Tool Hire is a company that, as you would have almost certainly guessed, hires out tools. While away on honeymoon (many, many years ago :P), Kerry-Anne and I stayed at a guesthouse on Knysna's Leisure Isle - and as it so happens, the owner of the guesthouse also owned Coastal Tool Hire.
Now, whenever we see one of these signs it brings back memories of boat rides, oysters, deep dark forests and that awesome guesthouse on Leisure Isle. :)
