Cause Moho is hard toho goho toho. Dres on the other hand is downright B-O-R-I-N-G, I mean its a scaled down Mun. I've gone a few times as a simulator for Moho probes and such, because they are quite alike. But other than having a colony, if you could call it that. Its quite large, however it is crewed by 3 Kerbs, all but 1 is a max security prisoner. They are in their own lander cans, and the guard has the only escape method, as well as keys. Guard rotations happen once an in game year. The arriving one spends 3 weeks on the surface with the leaving one, getting used to the prisoners, and all the systems. Each guard then goes to the station I have over Dres as a refueling/crew hub for long range, way out in deep space orbit type things. They then can return home on the craft I send every 6th month to resupply RCS and other materials, or they can remain as part of the QRF for the other guard should something happen. I have left a rover on Dres as well, it is a simple little one, with not much to it. I visited Dres on a high orbit once to show off some tourist what it was like over Dres, he paid me handsomely for it. I brought him back after his stint was up, he came in on a 6th month craft, and left just after the new year. It was more than what he wanted, however I wasn't about to send a craft right back after a few weeks to pick him up, just because you're a tourist doesn't mean that I will spend more funds than I have to, just to bring you home faster.
