Tonight: Drinks with a friend $15
Tomorrow: Tutor (+$30), bike ride to a local free museum/art installation ($20 for bike rental, $15 for potential food during/after)
Sunday: Race day! Race fee is paid for, $5 for public transit to/from the start and finish lines, $10 for Chipotle or some other large meal afterwards.
I also need to buy a few groceries at some point — $15 for that, $25 if I also go to CVS for face soap and dish soap and who knows what else.
