Giving my son a chance

I will be bringing my son up to Erie Co this weekend.  Of course the weather is crashing, but our windows of opportunity are defined by the calendar rather than the weather.  We're driving up from just north of Cincinnati on Friday night.  I've fished in the slush before, but I don't want to turn him off to the species before he gets a chance to connect.  I don't know the best approach to take.  Should I focus on getting out of the weather by targeting sheltered areas or fly in the face of the cold and target faster moving current like the creek mouths?  Any other advice?

OK, This raises questions.  How old is your son?  And is he the outdoors type.  My grandson fished with me from age 8, in all kinds of weather, and even in the slush.  But he loved the outdoors.  He had a friend who couldn't stand the cold if the air was below 45, and hated being in cold water, even wearing neoprene.
      All that being said; usually it is better for a 1st timer to keep to more sheltered areas  Try to fish moving water over deeper drop offs, and breaks.  This helps move slush.  And don't be afraid to go back to the truck to get warm. 
 

Good call on moving inland a bit.  The wind off of the lake wouldn't be something that I'd want to fish in...
 
A lot of good discussions on keeping warm in the winter on here.  Layers, angora socks, boot foot waders to lessen compression compared to sock foot, wool gloves, hand warmers, ect.  Definitely want an outer shell that will break that wind.
 
I'm with these guys, if he isn't gung ho about fishing, you may end up turning him off.  The steelhead are around after the thaw too.  Many meet their fate when the ice melts and crushes them, but many are around in more comfortable weather.  Completely understand the calendar thing.  I've fished in much worse conditions, since that is all the calendar allowed.  Best wishes on whatever you decide.
 
Forgot to mention, always great to take youngsters to Trout Run to watch the fish stacked up and jumping the falls.  Some of my best memories going with my Dad, was just watching the fish.  Of course, after 10 minutes, I was ready to catch one...  Not sure if you want to dare the lake front winds for that though.  Sunday looks down right brutal with 30mph gusts.  You guys would likely have no company fishing the mouth of Trout Run on Sunday...  Your casts might go backwards though.  

Well whaddya know, Saturday's forecasted high has now gone from 28 to 34, and only down to 24 overnight.  
 
If that holds, and that's a big if, I'd say you'll probably not have much to worry about in terms of slush and ice.  Keeping your son comfortable will be you biggest concern and you've received a lot of great advice about that.  
 
 

Why not fish the Ohio tribs?

Thanks all.  My son is almost 15.  Once he has wheels, I suspect adventures with Dad will fall off his calendar.
We fished Ohio last year.  It poured rain after about an hour fishing.  I haven't been back to PA in years, but it's where I cut my teeth.  I think PA has the best odds of getting him a fish.  Plus, you have places that will smoke it if we do get one. 
 
It only took one on with the reel screaming to hook me, so I can only hope the same is true from him.
