What's your most expensive hobby? (Past or present)

I saw this topic on a message board recently. We all have hobbies. How much money have you sunk into one, and do you have any regrets?

The easiest one I can think of was my paperback book collection. I read/collected Nora Roberts, VC Andrews, John Grisham, Sidney Sheldon, Christopher Pike, Nicholas Sparks, etc. Libraries, psh, I wanted to own them.  I didn't normally buy the books brand new, I searched used book stores, but it was still a hefty chunk of change.

Yep, own them I did. Where they sat in boxes after I moved from my Marietta apartment in 2007, and sat in boxes in Woodstock, sat in boxes in Columbus, and finally, when we moved into our house in Smiths Station, I pulled them out of the boxes and started listing them online to get rid of them for whatever I could. At first, I wanted to save the books in case my future kids had the same book interests as me. Who was I kidding? VC Andrews, even though I read those in high school, were garbage. Filth that I shouldn't have read, and filth I certainly don't want future kids of mine to read. Nora Roberts was the typical smut novel, but those will always be around. The rest...well, I just didn't have room to set them on a shelf, and I decided it was pointless to keep them in a box.

I've sold quite a few in the last few months, but I'll be taking the rest to a yard sale at the church at the end of the month.

What's been your most expensive hobby?

Thinking about starting another blog....

I've been thinking alot lately about starting a new blog that's not necessarily about my personal journey, like this one, but something designed to be a benefit to others. I'm at a stand still trying to figure out the theme of the new blog. I want this to be a blog that can possibly grow outside the readership of just my Facebook friends.

I've been thinking about finances from the view point of a young military family, or a college student. 2 areas I have personal experience in, and two times of my life if I had known then what I know now, how much different my life would be. The problem is, I'm not sure if I can incorporate both of those and it be effective for both audiences.

If you fall into either of these categories....military (or family) or college student, or just out of college,  would you be interested in a blog like this? A blog about finances from a realistic point of view rather than telling you to save 25% of your paycheck when you can barely afford to put gas in your car to get to work? If yes, are there any specific topics within this theme that you would like to see?

If you have any comments or suggestions, I'd love to hear them. Thank you!
