There is a dangerous sinkhole on the 4800 block of Baltimore Avenue. A reader Joe described it as about two feet deep and stretching at least a couple feet in either direction. It is in the middle of the bike lane on the north side of the 4800 block, in front of 4827/29.

“Don’t let its demure appearance fool you. It wants to eat you and your bike,” Joe warns.
 

A German Shepherd/Pit Bull mix has been missing for some time in the West Philadelphia/University City area.

A 36-year-old man was mugged by 10-12 young males on the 4600 block of Chester Avenue on Monday night, police said.

Police say the youths punched the man, who was a house guest at a nearby residence, and stole his cell phone and laptop at about 11 p.m. He refused medical attention. The youths were not armed and no arrests have so far been made.

The West Philly resident with whom the man is staying wrote us that:

“It seems like there has been an uptick in muggings in the “triangle” between Baltimore and Woodland and 40th and the Kingsessing rec center which is usually pretty quiet compared to the main East-West streets (Walnut, Spruce).”

A neighbor Susan is searching for her cat:

My 15-year-old Russian Blue male cat Crumb went missing something yesterday, June 20, in the vicinity of 49th & Springfield. He is rather thin and has had some dental surgery that has made eating anything other than watered-down canned food difficult.

If you think you’ve seen Crumb please email Susan at susaniris [at] msn.com or call at 215-435-5273.

We are all getting used to fun stuff happening every weekend here in West Philly, but here’s something to enjoy in the middle of the week and for a very reasonable price. Penn Museum (3260 South Street) presents a series of concerts this summer (through August 24) every Wednesday night from 5 to 8 p.m.

All performances take place outdoors, in the museum’s Warden Garden, so you can enjoy some fresh air after long hours at work. Refreshments can be purchased at the venue. Tickets are $5, which includes admission to the museum.

This week “Summer Nights” features Baris Kaya and his band, Barakka, who mix Turkish folk, Middle Eastern and rock music.
 

People in Philadelphia woke up to loud cheers from some West Philadelphia YMCA members yesterday morning.

Here’s the video.
