Interacting Systems with Young Star Clusters Antennae Galaxy; Selected Star Fields NGC 3256 More Examples
	Giant Molecular Clouds (GMCs) as Cluster Progenitors
	How do Stars Ordinarily Form in GMCs? Inefficiently At Sluggish Rates set by Ambipolar Diffusion Not as Bound Clusters (because e < < 50%)
	How Can the Bombs (i.e., GMCs) be Ignited During A Galaxy-Galaxy Interaction? Cloud-cloud Collisions? (an old-time favorite) Environmental Over-Pressure (Jog and Solomon 1992) Move the GMC into an Environment where the Cosmic-Ray Flux is Low
	Summary GMCs make superb bombs. The bombs can be ignited by the environment without resorting to violent, gas-dynamical triggers. What about young clusters in the LMC? Any Evidence that this Works? [NGC 4038] [M82]
