how to spend my bday?

Hey B’s! Tomorrow is my birthday and I was planning on taking a day trip up to cold spring to hike/lunch and bop around. I was going to do this solo since my friends/fam have to work during the day but I have dinner plans with them at night. I’m really bummed I have to cancel my day trip bc of the rain and I’m having a hard time figuring out what to do during the day in the city on a rainy day :/. Would love some suggestions!
