@jmmzpsu14 - Regardless of what the id of your tree is, that is a nice compact root system, this tree definitely has possibilities as bonsai. Pinus rigida and Pinus echinata are in the same sub-section of the genus, they are close enough related that they hybridize where ranges overlap. Both have the habit of epicormic sprouts. Pinus virginiana is in the "Contorta" sub-section of Pinus, related to Lodgepole and Jack pines. The Lodgepole, Shore pine, & Jack pine group have a good track record for bonsai, so no matter which it is, it is good for bonsai.
Pinus rigida - needles in bundles of 3, frequently twisted, 2 to 5 inches in length (6 cm to 13 cm length) and relatively stout compared to EWP.
Pinus virginiana - usually needles in bundles of 2. Needles usually 0.75 inch to 3.5 inches, (2 to 8 cm) usually twisted, sheath at base of needle bundle is greater than 2.5 mm in length.
Pinus echinata - needles in bundles of 2 and 3, on the same tree. needle length 2.75 to 4.25 inches long (7 cm to 11 cm length).
Eastern White Pine, Pinus strobus - has needles in bundles of 5 and is a mediocre, problematic species for bonsai. Not impossible to create bonsai with, but definitely requires skill and luck, generally results are disappointing. Needles too long, internodes too long, insufficient back budding to remedy the first 2 problems.
