I am 50 miles from you Flex. I know your area well and I can tell you for certain bee's thrive here. We have maple trees in the spring followed by dandelions, honeysuckle, Blackberrys and one of the most important, Nap Weed as well as others. I have never seen any area around us that did not have lots of goldenrod in the fall also.
Never had a problem getting bee's to move up in any package I have purchased, and to thrive. I have seen packages get honey bound fairly quickly here in our area and cast swarms because of lack of room for the queen to lay. This can happen in early early June especially if your feeding them. If you are going to use drawn comb or if you buy nuc's their going to out grow that first box quickly, at least in 8 frame Mediums. Usually buy the time you can get nuc's here (end of May) the flow has been going for a couple of weeks. I generally only feed my package bees until the flow is on good. Then their pretty capable of building and maintaining the hive on their own. I do watch my package bees carefully and inspect them every 7 days.
One last thing. Varro Mites thrive here! I treat every package of bees after I hive them within the first 4 or 5 days..
