I haven't been up to Tydings Park boat launch in Havre de Grace in quite awhile. What is the procedure for paying the fee to launch a boat. I plan on getting there before sunrise. Do you still drop off an envelope in that trailer? In the past, the few times I've been up there, there seems to be no one around to collect the money. Can I supply my own envelope with information like truck tag etc. and is there a mail slot to drop it in, and is it still $5.00. Or is there a better ramp in that area that someone could recommend? Thanks in advance.
