I'll usually have one for my expeditions to unknown lakes, out in the brush...my lady and I do a lot of hiking into "less fished" waters. Ya never know when you'll run across something hungry, or some tweakers...or a grow-op.
Usually, if it involves a backpack, a fishing pole, or a hunting license...and I can legally do so...I will have something with me.
More than often an XD-40, Ruger Security Six in .357, or also somewhat common is a simple .22.
That being said, I don't concealed carry on a daily basis...I don't see *much* need given the area's I live and frequent. If I ever get something smaller/lighter, I may consider it...but not at this moment.
