Replying to Ideas of stuff to do in Boulder Colorado

I'm in Colorado for a week going on a couple of college tours and am stopping in Boulder for two days. The first day is going to be touring the campus of the college but I have no idea what to do the second day. My dad and I could easily spend the whole day going from ski shop to ski shop just browsing stuff but my mom is with us as well. Any ideas what we could do as a fam? We'll probably walk around town for a while but are there any good hikes around? Just throw some input down below and if you see a dumbass in a NS five panel and two touristy parents feel free to flip us off or say whats up.
