i looked at U of MD and there isnt really any skiing all that close. i ended up at LaSalle, pretty much up the street from temple. bear creek, blue mountain, and big boulder/jack frost are all easy day trips. quickest way out of the city is broad st. north to 1 south, 76 west to 476 north. depending on traffic, that could take 15 minutes, or an hour if you time it wrong. from there, bear is a little less than an hour, blue about an hour and 15, and boulder about an hour and a half. philly's got lots of handrails too, but it seemed everyone was travelling or hurt whenever it snowed last year.
used to be at lasalle, i graduated in 07 and live in rox now. the pretzel rail in manayunk needs to get slayed, and there's a really good one at an office building on chemical rd in plymouth meeting with a perfect inrun.
From UMD, you have Ski Liberty and Ski Whitetail an hour away with maybe some change. Roundtop will be about 1 hour 45 minutes. Wisp will be about 2 and a half hours; Seven Springs is maybe an hour more. If it matters, Liberty Snowflex in VA is about 4 hours away
