Yarly - there are also some golden comments on his article; some people calling him on judging 'some' hobbies as being 'suitable' for post-college adults, while looking askance at others. What, is age '30' some 'magic' threshold, too? Creatinf a fantasy character for SCA? Ooo, you economy-threatening slacker you. But 'fantasy football' is just fine...
Other commenters question whether material costs, sewing machine (and serger) purchases and maintenance, plus travel, hotels, & eat-out meal expenses at cons should instead be seen as a STIMULUS to a local economy, ne?
Enjoy!
