I'm a male, 54 yo, but I'll be 55 by Christmas.

I collect cookbooks, the kind with regional recipes from wherever it is you live, especially the kind put out by organizations (schools, Fire depts.), for fund raising purposes.

Also, Mudcatter CD's,(especially Country music in any form), Mudcatter crafts, mudcatter-authored books (the kind that can be read for pleasure), ocarinas in unusual shapes, antique glass bottles, and old postcards, especially the kind that say "greetings from" and then the name of the place in big letters.
also, any books about wherever it is you live - local history or picture books. (If you are a coastal dweller, I like lighthouses.)
