You really have to head to Michigan to get more sand around here......
Log Road - Relatively close and pretty sandy soil about 2:45 from Westlake.
Baja Acres - Really Sandy, deep deep sand, but is about 4.5 hours from Westlake
Motoland in Indiana - Really Sandy, not quite as deep as Baja, but all sand all the time. About 4:15 minutes from Westlake.
Red Bud - Mix of sand and dirt, but sandier than us Ohio guys are used to, 4 hours from Westlake.
Dutch Sport MX - Fairly Sandy as well, but has hard under surface. about 4.5 hours from Westlake.
Silver Lake State Park in Michigan is a Sand Dunes riding area, so if you are really missing your sand, you can ride there but you have to mount a flag to your bike to ride there, which is kind of a pain in the butt. But it's DUNE riding like they show out west at Glamis type stuff. About 6 hour drive from Westlake there.
