I didn't read the Hardy Boys . . .

. . . but I read The Three Investigators. I couldn't even remember the name when I mentioned this to Pete the other day. Just the main character, Jupiter Jones, and the headquarters in a junkyard. Turns out, he'd read some of the same books. And also couldn't remember the name of the series. So I thought I'd look it up and see if anybody else remembers these. :)
