Hey buddy,
I love fishing and over the Xmas break I had to turn down several similar offers with old buddies who smash the beers while out on the boat. Instead I spent 3 days exploring the countryside inlets fishing solo. It was fantastic and I felt truly at peace, wetting the line and catching some big dusky flatheads solo. It was a good alternative for me.
Maybe it's too early to be in a risky situation like that, but you can still enjoy a fish alone or why not invite a new bud from aa?
Good luck
