Yes! I feel ya. For sure.
Well, for one thing, I have to DRIVE somewhere to go walk. I live on 3 acres with 90 acres of farm behind us. No sidewalks or neighborhoods, we're just on a main road. So I can't just walk out my door, so I drive and it's only about 3 minutes up the road, to a nice neighborhood with sidewalks and park in their golf course parking lot and then walk the neighborhood. So even though it's so close, sometimes I just wish I could walk out my front door, I cannot wait til I'm living in a neighborhood again.
But I always get bored. I know Jackson could keep going, and I surely SHOULD keep going for the exercise, but after about 35-45 minutes, I'm just ready to stop simply because of boredom. I've been considering bringing my iPod but I'm always so paranoid about having music in my ears while walking by myself because I feel like I won't hear something important, or someone will creep up behind me, LOL. I don't know.
I never tire of watching Jackson at the dog park though. I've often stayed for 2-3 hours just loving watching him RUN and be free and happy.

Also my dads fenced in back yard, I love watching the dogs all run and play together.
