Dave, Welcome to the Free State, and thank you for your service!
I do not currently have a "big" adventure bike...but do have something that is more than capable of hauling off some GWNF miles. I'm in Ellicott City, 36 years old, and if you were looking for company to hit some off-road me and my DRZ (pictured sans luggage) would be up for that. (maybe send me a PM and we can make something happen?) Also, I love the Groms--but I already have a 44 year old one!???(no insult intended)
