We can play in Gerbrandypark (map). It's astroturf (like the Sloterdijk pitch) and it has lights, which means that we can start after dark, say at 6.30 PM.
The main problem, however, is that the lights are not very bright so that the pitch is only sort of dimly lit. It's more or less playable, but not everybody will like it.
Another problem is that there is a good chance that others are either already playing when we arrive or will want to join us later. It's a public court so we can't claim exclusive use of the pitch. For some people this may be a deal breaker, for others it may not be. That's everybody's own choice.
Please sign up if and only if you are going to come (or cancel as early as possible if you signed up but then find out you can't make it), so that everybody can get a good sense of how many people will be there.
There are a couple of crucial points to keep in mind about outdoor games.
1) It is not possible to reserve outdoor pitches (I've tried everywhere I could think of, but couldn't find any pitches that could be booked in advance. If you know of one, please let me know). This means that the pitch may be being used by other people when we want to play, and so there is no guarantee that we can actually play there when we want to play, and we won't know until we actually get to the pitch. There is nothing that can be done about this.
2) It may rain. A bit of rain isn't so bad but more than a bit becomes problematic, also because fewer people will show up then and we may not have enough players for a good game. So if it is expected to rain when we play the game will be cancelled.
3) The upside of it being impossible to book the courts in advance is that they're free to use, so outdoor games are always free.
4) If you have special shoes for artificial grass I recommend using them.
