Exactly mate. Be safe about it. The rule is, if you have to go out once or numerous times, then maintain the social distance required and keep yourself and others safe.
Which, and this is the thing, even the vast majority of those people who were getting slammed as 'idiots' for going to parks in big cities last week were doing.
Obviously, the ones who were sunbathing or having BBQs - that's a different story.
But most of those pictures of parks, while they showed a lot of people, showed groups of max 2 (unless they were clearly families) all spread apart and following the social distancing rules.
Going to a park isn't and shouldn't be a crime, especially if it's their only option for a bit of greenery and exercise.
I've left the house once today (well, I came back, but stayed out as I went straight from a run onto a bike ride - just trying to push myself as best I could, though i know I'm only supposed to do one form of exercise). But I kept my distance, as everybody else does and I'm lucky I have rural areas within five minutes of where I live in three directions.
Think my mum has left to go care for my gran and my dad left to go on a bike ride and then to the supermarket.
It's just about being sensible. The most dangerous thing any of us three did today would have been my dad going to the shop, but obviously the store is following the measures and everybody who goes is, too.
