Lets see if I understand these symbols correctly:

1) No marching with roller skates on and a muffler/shawl round your neck.

2) No threesomes.

3) No wolf/wild animal allowed in

4) Don’t use bicycles with two seats and no handlebar.

5) Don’t stand on the trolleys 

6) No smoking.

I must have got at least one of them correct! What do you think?
