Such nice shots. Looking forward to what you can produce this spring, PF, which starts...today! Happy Spring! More than ready for it.
As for the thought of using a bike for photo jaunts: I encourage you to pursue that. I've found a bicycle to be a great way to explore for photography, mostly because you move at a pace that really allows you to take in details around you, which a car sometimes passes too quickly to allow. I've rigged various bikes for carrying stuff, but the one I set up specifically for the purpose does the best; I move a bit more slowly on it than some of my other bikes, but it's very comfortable and can carry quite a load right up front where I can keep an eye on it, so idea for my large format stuff.
For those who haven't seen it before, here's a shot of it that gives the general idea:DP2Q0093, Kogswell P/R quarter view

For the gear-curious, I built up the bike around an 8-speed internal gear hub to improve weather resistance (No external derailleurs to get crudded up in the rain or mud on dirt roads; allows for a chaincase to protect the chain, which I ought to install one of these days) and a French "porteur"-inspired rack; the geometry of this particular frame is designed for a front load. I have a porteur bag to go with it, and I can fit all manner of gear in there, up to 8x10 if I wish. Have only had the 4x5 rig out on it so far, but hope to do better this year. Rides like an ocean liner getting under way, just a smooth glide...
