Returning to skating after a long layoff (I'd blame it on my running injury, but truth be told I was slacking before that!). I'm a beginner, had gone through the Adult ISI Beta previously. I'm pretty sure I need to have my blades sharpened as it has been a long time- but how do you know for sure when it is time?? I'm also looking for recommendations on where to take them in the DC area- I had purchased the skates at Blades of Bowie and took them back there for sharpening once- but no idea if that person (I think his name was Chip? Or Chuck?) is still there. I also wouldn't mind finding somewhere closer to DC proper. Any recommendations from other DC metro skaters? Thanks!
