I'm living out of town in a small farming community. The local youngsters have done the usual splashing cars and motorbikes on the main road; but it's more of a family thing with us - quite an extended family live in the same general area. Can't remember the last time it rained here, but I'm sure water will be found somehow.
A few years ago I did the compulsory Songkran thing in Phitsanulok city - similar to Bangkok streets. Fun once, but over it now.
