Re: what kind of blimps are flying near you?
Last week a MetLife Blimp was circling Harrisburg on a Saturday.
And a few days ago, there was a Ford(?)/Fokker(?) TriMotor doing a great circle around the area, probably giving rides, taking off and landing at New Cumberland airport on the West Shore of the Susquehanna River.
Blimps: a source of topping-up helium for the ballonets might be found as close as your neighborhood grocery store or dollar store, if they sell gift/get well balloons. One tank might not be much, but if you scavenge a couple of malls and shopping plazas, yuu could garner quite a reserve for replenishing gas lost by leakage/gunfire.
