Welcome home as well! No, your not crazy. I do the same thing except I do it like OBG suggests, on your hands and knees. As any of the other firefighters (i'll have 19 years in Sept)on here can tell you the air is significantly cooler, cleaner and much easier to see through! I can brag that my 9 and 6 year old daughters can climb out and down the escape ladder in their room faster than I can!
