I figure, if you go to a play area on the weekend they re-open, you have accepted the risk as they are bound to be busy! We went twice on Saturday and twice on Sunday and this week, we are going to a different park every day.
We love our local park and typically go for an early walk at 7am, then sometimes a second walk at 8.30am (if we can't be bothered to go for a longer bike ride) and then return later in the day for a longer run around and play. Adding the playground into this, I expect we will be there several times a day in the summer!
I believe my family has had covid19 already - can't be certain but seems pretty likely based on symptoms we had. We are all in excellent health and I'm not too worried about catching the virus. I'm more worried that my kids aren't getting enough exercise and my toddler's immune system will be crap because he hasn't seen anyone in months - I WANT him to encounter some germs!
So, we will go to the playgrounds, attempt to respect the rules, wash our hands, and not worry too much if the social distancing fails. I'm truly not concerned at all about germs on play equipment! My kids and everyone in the neighbourhood has sat on one single metal bench in our park, and we are still ok.
I never understood why it was apparently lethal to go on a swing or slide, yet every old person and parent with their kids would pause on this metal bench, often to have a snack or a drink, and NOT ONCE did I see anyone use hand gel when they got up. Totally stupid.
