Pennsylvania lobbyist gift rules are the topic of this editorial at Themorningcall.com. 

[I]n 2006, the commonwealth adopted the Pennsylvania Lobbyist Disclosure Act, a public reporting law. It required a lobbyist’s employer to report gifts worth $250 or more and entertainment (meals, hotels, golf and trips) worth $650 or more to an individual elected official or public employee. It was a decent step forward.

But, it left an easy-to-access loophole. Keep the spending at $249 or $649 and no public disclosure is required. Or, a lobbyist could take several legislators to dinner and spread the spending amount among them, also avoiding the required reporting on what turned out to be a rather big-ticket event.
