.biz .biz and geo names?

[doggyowner]

I would appreciate your input on the following dilemma I have

I have come across some available city names, both US and Global, population is 50k to 100k and above.

The .biz extension is available, most others are taken.

Are they worth regging? Has there been any notable geo domain sales with the biz extension?

Thanks..

I have a few biz geos myself, but I generally look for higher populations than 50k at this point, or at least being a resort location. I think you need maybe 2-3 times that to get enough traffic to pay renewals unless you develop it. I think they will make good business directories when developed, and have future value. I not only look to see if all other major TLD's are taken, but if at least something other than .com is developed.

A few of mine:
HamiltonCounty.biz
ClevelandOhio.biz
CincinnatiOH.biz
DallasCounty.biz
CityofIndianapolis.biz
ParkCityUtah.biz
MammothCave.biz
