Strangely, pine cones like these remind me of school days and holidays. The school that I attended for grade 1 through 7 had several pine trees on the property, and I remember playing marbles amongst the trees during break (which you might know as "recess" if you're not a local), as well as picking out and eating the pine cone seeds. Not because I was hungry, but because they were so yummy! :)
The cones remind me of holidays because of the times that we spent at caravan parks during school holidays. Often parks would have plenty of pine trees to cast shade over campers' tents. The downside of this was that they were notorious for dropping sticky gooey pine gum onto tents, caravans and cars. :(
