Thanks Matt! Maybe you can ask the Southampton Council to put some chess boards in the parks, but they might object saying they need the funds to buy expensive biscuits for their productive meetings or a new CCTV system or more traffic wardens...
Actually asking the Council (local gov't) is a good idea. From what I've seen park life is just as big in the UK as it is anywhere else. I live 5 minute walk from Victoria Park and 15 minutes walk from London Fields and there were hundreds of people enjoying the outdoors today. London Fields has a permanent stone table tennis table with a stone net that a group of kids were playing on today. I also heard today that Vicoria Park is getting a 10,000,000 pound upgrade in preparation for the 2012 Olympics. Surely they could kick a few quid to get some stone tables with 64 squares on them. If you build it, they will come.
And to answer another question, yes you have to bring your own pieces (and brush the leafs off the table top:).
And thank you to the Canadian who posted the info about chess in Hollannd Park.
I know that chess is played near the Lake Michigan beachfront in Chicago, but I have never played there. I beleive it is North Avenue Beach.
