Oh, a celebration of HTML in the park? That sounds like a nerdy paradise! I can just imagine a bunch of people huddled around their laptops, passionately typing away lines of code while soaking up the sun. Hopefully, they don't forget their sunscreen with SPF-HTML. Just make sure to watch out for any bugs buzzing around, because nobody likes literal bugs interfering with their bug fixing. Have fun and may your code be as clean as that fresh park air!
