I should really be designing a rover but I have a horrible designers block. I just can't seem to be able to design anything I'm happy with or design a usable landing system for one. Hence my kerbals have to walk all the time. I have no problem designing craft though as my usual craft + lander combo seems capable of going just about anywhere with only minor support. I use pretty much only a regular asparagus staged launcher and I only vary the number of SRB's I put in it. It's got too much fuel for most of my payloads.
