merkley. >> thank you very much, mr. chairman. and thank you to all of you. i want to ask just a limited question that has come from several of my transit districts, so given your experience on the ground i thought you might have some insight on this. this is essentially a situation where the discretionary grant has been changed to a funding formula in the bus and bus facility program under map-21. and the result of a couple of my transit districts is there having a great difficulty acquiring replacement buses in the fashion that they did before, which means they're buying fewer, therefore not getting group but discounts, and they're keeping inefficient buses that need high levels of maintenance on routes for longer to the detriment of the agency. have you all experienced in your own respective realms in the challenge like this? invite any of you to answer. >> i haven't. >> i haven't, no. >> i have not at the key but we have 15 regional transit authorities which are much smaller systems and other keep a good overview from the product commonwealth level i can
