Today, more than ever, local authorities are facing unprecedented demands in relation to funding facilities such as sports centres and local parks. There are many factors to take into account when deciding how to allocate funds.

While many people regard sports centres as places to merely enjoy different forms of exercise, it is important to also consider fringe benefits. Having increasing demands on our time in the form of long working hours coupled with commuting, spending time playing sport not only provides the opportunity to experience the thrill of competing but it also
provides an environment conducive to social interaction, both during the match or activity and while relaxing in the bar afterwards.  Although playing with friends in a semi-competitive atmosphere is the most common approach, it is often possible to take a course or have individual sessions with a professional coach.

The advantages previously discussed might suggest that this is an open-and-shut case. However, there are reasons for choosing local parks which many would say outweigh those of sports centres. Imagine an elderly couple holding hands sitting on a bench while excited children are climbing on play equipment a short distance from a group of their mothers who are chatting while keeping a keen eye on their offspring. In the distance, tennis courts and a bowling green are in continuous use. At any time, the participants and observers can take advantage of the all-day café which provides delicious, tasty snacks as well as a light lunch.
Naturally, there is a cost in terms of cutting the grass and maintaining flower beds, but the staff and equipment involved are usually in operation at several such locations.

Individuals might choose based solely on their personal preferences, but local authorities need to look at the wider population. The opportunity to be in a safe haven away from the pollution of the city, not to mention streets clogged with traffic, gives local parks the edge in the eyes of many people. 328 words.
