Combined the 2007-ish and 2008-ish Hagerstown tracks. The track model and grandstands have actually been completed since 2014, I just never did anything with it.
If I forgot anyone else let me know and I'll add you.
This track should work with both .3 and .4. If you come across any issues let me know in the comments below or PM me and I probably won't fix it. Enjoy!
