I-69 is a good road all the way to Lansing MI. 1 construction spot north of Ft Wayne but its just a lane shift, still fast. Watch for State Trooper MC around Ft Wayne. They get alot of folks. Stay on 69 through ft wayne dont go around it on 469. 469 is the looooong way. 69 is 6 lanes through the fort.
Funny you say Warren Ind cause I'm stationed there today.

2 hotels here. All new within 10 yrs or less. The Motel 6 is very cheap. I think it says $49 on the sign. I'll look later today. Also a no-tell motel but i'll leave that one out.

Mc D's, family resturaunt, and Steal City truck stop all out front. Also a gas staion with a subway. You need a cold one you gotta venture into town to the only bar about 5 miles. They got very good food, better then the resturaunt.

Warren is very safe and quiet. Town has like 7,000 people. Nice short rides along the river are kinda neat.
Anderson. Big town with alot of hotels and food. Stayed at the Lee's Inn once and was good. If I had to choose and could ride another 50 miles, I'd choose Warren.
Weather is good for monday/tue. 85 and no rain.
Let me know what you decide and when you will be up this way for a possible hook up. I work mon at a different station but tue is free.
Update*** Motel 6 is $35.99 per the light up sign. It never changes.
