Yep, it is national pancake day in the US and apparently there is an international pancake day next week. (saw it this morning in a blog I follow).
So geo, sign up for pinterest. It is free and has a zillion ideas for things to do. Maybe you need to find a book club. Or branch out into an area of cooking that is more involved than just making dinner. Like making cheeses. Or something non-edible like Christmas Ornaments, or bath salts/lotions and potions. Photography can be very inexpensive as long as you aren't printing a lot of stuff. You can take a photo and use different Photoshop type programs to make alterations to it or combine photos, etc. Maybe take a drawing or painting class from your community education classes-or just see what is offered there, maybe something will strike your fancy.
We did geocaching years ago when DS got a GPS for Christmas. His birthday is Groundhog's day, so we always left a wooden nickle with an etching of a groundhog. It was huge fun. Not sure why we stopped.
