What is the fine-grained topic of the following text: On Sunday 4th November Clive H myself and Sandra travelled up to Heathrow to put on a club display in the Heathrow Bonsai show, the weather was atrocious going up raining all the way, marquees had been put up but the rain was being driven in through any gap onto the tables so it was decided not to use our backdrops and cloths. Only return the topic.
