just some maple tree photos mostly

i went to the park with the intention of looking at the sugar maples to try and fins an identifying characteristic...i was defeated in this and will still be looking around...what i found was tapped trees both with and without copious buds..including ones they lost in last week's storms ( photos 1 to 6 )...the ones in my yard lost buds as well ( photos 7 to 9 ) and the ones that are left on the trees today ( photos 10 and 1 ) don't look nearly as green in the newly cold weather as they did a couple of weeks ago ( last photo )...the weather is due to warm again by tomorrow...we'll see what they look like mid-month
