We argue that, when compared to AGNs in dynamical terms,
microquasars are found in low density, low pressure
environments. Using a simple analytic model, we discuss radio lobe
dynamics and emission. Dynamical considerations for GRS 1915+105 and GRO
J1655-40 show that they are located in regions much less dense than
the canonical 
unless the jets are
unusually narrow or much more powerful than currently believed.
Key words: galaxies: jets / ISM: jets and outflows / stars: individual: GRS 1915+105, GRO J1655-40
