Meh suggestions, find a farmland nearby where you live and see if there are any rivers with dykes and go for a stroll there. The parking along them isn't usually too big though.
As an example you can lookup Harris road bridge or Neaves road in Pitt Meadows on the map as there several spots along to go stargazing/observe meteor shower.
Word of warning, I am not sure how much I can recommend those two specifically anymore as they did get very busy last summer during peak...unless you come out before nautical/astronomical twilight.
