Too Laggy with a limper?

[RustedCorpse]

Party Poker 2/4 Hold'em (10 handed)
Pretty Tight table. UTG+1 was fairly loose passive, calling down with Ace high a few times. Other wise the table is slightly tighter thank I'm used to.

Should I have just mucked preflop?

Not sure you can call the river.
