Yes, it is very unusual for the Summer! I've lived here 15 years and there's never been this level of activity, day or night. Daytime is fine, I appreciate this year is different and people need to get out, especially with the good weather, and it's actually nice to hear the buzz. I also appreciate that people would ordinarily be elsewhere, maybe at friends, family, the pub, club, holiday, but hanging around in those numbers, making that amount of noise, that late at night, in a closed, locked park, and leaving that amount of litter, is just massively inconsiderate, careless, selfish & thoughtless - the very definition of anti-social? Maybe I'll try 101 next time, but last time I did that (after having bikes stolen) I was amazed to find it had cost me several ??s, for no benefit...
