Hey Ari !!
Here in Maryland gas prices are anywhere from $2.90 to $3.50 per gallon. It can get pricey to do a lot of driving. As far as Hockey tickets, i belive that the Hockey season ends in April, so i don't think there will be any games to see, but tickets for a Washington Capitals game do run about $100 or so for good seats, i am sure there are cheaper ones though.
I live right outside Annapolis, and only about 30 miles from washington dc, give me a call if you think you will be near me anytime. Been talking to you on here for a few years now, it would be nice to meet you !
I'll PM you my number.
