ive searched, and couldnt find a definite answer. i have yet to get the room at the 38, and wanted to do cass's quests. i released boone, and took cass. ONCE, i happened to find him in a house -i swear was around issac the gun runners house- he said 'time to join up again?' i said no, as i was still with cass. it was a plain, beat up house i thought in that area. now i have the suite at 38, released cass, and cant find boone. where is he? not at novac anywhere. i cant find the house i saw him in last time.

He sometimes walks across the motel area in the daytime. At night he is always standing guard in Dinky The Dinos mouth. If all else fails, move it to past midnight and go to the dinosaur.
