Sledding Help

We are wanting to take our kids sledding this weekend and I was needing some help with it.  The first is where should we go?  Any suggestions?  The other is that we discovered when it snowed earlier that our boys have grown out of some snow gear.  Would anyone have a size 10/12 bibs (or pants) that our 10 year old boy could borrow and our 7 year old grew out of his snow shoes.  Does anyone have some snow boots in size 3?  Please e-mail if you can help with anything at elpinons{at}yahoo{dot}com.  THANK YOU!!!!
