3-4 day a week delivery sounds good, but the execution would be filled with problems, first and foremost is space in the vehicle for two days worth of mail. Even if they had minivans the sheer amount of packages would be prohibitive. Add on top of that ten+ trays of letter mail and it would be too much for a van to hold. Sorry, but its very hard to cram mail into a LLV the day after a Holiday. Now you'd be having at least 100 "holidays" and our system isn't set up for that. It would break the system and then we'd need a complete overhaul and that would cost ooodles and booodles of money. I hate to be a negative nellie, but the reality is quite different than good logical ideas.
