I attended HCSSiM in 1994 and 1995. There I made some great friends, learned tons of math, several card games, and how to juggle, started to collect yellow pigs, and generally had a great time. I've also been back for many YP day celebrations (1996, 2000, 2001, 2003, 2004, 2005, 2006, 2008, 2010, 2012, 2017, 2023). I welcome email from past, present, and potential future alumni.
