Hot steering column

went to the not so local ice cream joint for a cheese burger and fries tonight. About a 30 minute drive there and 40 on the return trip. When I backed into the garage and shut down I noticed the steering column was hot. Not smoking hot but hot enough to get my attention, around 110 to 120. I can't think of anything other than the ignition and turn signal switches in that area. All ideas of what else to look for when I pull the wheel wil be appreciated.
1970 Swinger 340 4 speed.
Thanks in advance, Jerry
