I'd love to meet people, and my calendar is totally open (on weekends) for the rest of this month. After that, Saturdays are usually open and Sundays often taken.
However, I have no plants to share. I would bring my rather large seed collection, including many older seeds.
So I wouldn't take plants home unless someone wanted:
a heavy steel-wire shelf suitable for supporting hardware cloth for a wheel-barrow-sized sieve.
propagation trays / plug trays (I have extras of a few sizes, plus some sizes I never seem to use)
plastic yogurt tubs, will drill 1/4" holes if wanted
many 2 liter soda bottles (will cut off tops & drill holes if wanted)
a tub of all-nitrogen urea fertilizer (46-0-0)
WW I bayonet and/or used stainless steel knives, for weeding
gray-painted steel "angles" (uprights for steel shelving, suitable for strong posts)
variety of sprayers, spinners and odd fittings for irrigation systems
